Version 3 of the epic saga: [PATCH 3/4] Make system enhancements.

========
HISTORY
========

Draft 1:
1. Write up a document on how to use the new Make system
(README.mk-devel), so others may assist in the work that we're
spearheading at Cisco and contributing back to LTP, and we can begin
dropping the adhoc Makefiles.
2. Add master_rules.mk which contains canned rules for environment
setup, leaf directories, and trunk directories to reduce Make logic
noise in the existing LTP Makefile's. This is a more condensed and
straightforward version of the original master_rules.mk file
contributed and never integrated into LTP in the past.
3. Add master_include.mk, a file which stands as the defacto include
Makefile for all . This was created out of the comment provided by
Mike Frysinger w.r.t. a master include file.

Draft 2:
1. Addresses issues brought up by Mike Frysinger in draft 1 review.
2. Fixes several bugs found through continued testing.
3. Adds lib.mk, testcases.mk to create more structure in Makefiles,
and prevent ad-hoc structure with libraries and testcases/ directory
binaries to reduce code duplication.

Draft 3:
Address all outstanding comments by Mike Frysinger in draft 2 review.

+==============================
+Introduction
+==============================
+
+The following document briefly describes the steps and methodologies used for
+the new and improved Makefile system.
+
+==============================
+The Problem
+==============================
+
+The problem with the old Makefile system is that it was very difficult to
+maintain and it lacked any sense of formal structure, thus developing for LTP
+and including new targets was very more difficult than it should have been
+(maintenance). Furthermore, cross-compilation was impossible due to the fact
+that the Makefiles didn't support a prefixing system, and the appropriate
+implicit / static rules hadn't been configured to compile into multiple object
+directories (easy of use / functionality). Finally, there wasn't a means to
+setup dependencies between components, such that if a component required
+libltp.a in order to compile, it would go off and compile libltp.a first
+(easy of use).
+
+These items needed to be fixed to reduce maintenance nightmares for the
+development community contributing to LTP.
+
+==============================
+Design
+==============================
+
+The system was designed such that including a single GNU Makefile compatible
+set in each new directory component is all that's essentially required to
+build the system. Here's an example of how one would accomplish that:
+
+.../foo/Makefile:
+#
+# Copyright disclaimer goes here -- please use GPLv2.
+#
+
+srcdir			?= ../
+
+include $(srcdir)/include/mk/master_include.mk
+
+$(eval $(generic_dir_target))
+
+.../foo/bar/Makefile:
+#
+# Copyright disclaimer goes here -- please use GPLv2.
+#
+
+srcdir			?= ../
+
+include $(srcdir)/include/mk/master_include.mk
+
+$(eval $(generic_leaf_target))
+
+==============================
+Make Rules and Make Variables
+==============================
+
+When using make rules, avoid writing adhoc rules like:
+
+[prog]: [dependencies]
+	cc -I../../include $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) $(LDLIBS) \
+	    -o [prog] [dependencies]
+
+etc. This makes cross-compilation and determinism difficult, if not impossible.
+Besides, implicit rules are your friends and as long as you use `MAKEOPTS=;' in
+the top-level caller (or do $(subst r,$(MAKEOPTS)) to remove -r), the compile
+will complete successfully, assuming all other prerequisites have been
+fulfilled (libraries, headers, etc).
+
+$(AR)			: The library archiver.
+
+$(CC)			: The system C compiler.
+
+$(CXX)			: The system C++ compiler.
+
+$(CPP)			: The system C preprocessor.
+
+$(CFLAGS)		: C compiler flags.
+
+$(CPPFLAGS)		: Preprocessor flags, e.g. -I arguments.
+
+$(CXXFLAGS)		: C++ compiler flags, e.g. -I arguments.
+
+$(DEBUG_CFLAGS)		: Debug flags to pass to $(CC), -g, etc.
+
+$(DEBUG_CXXFLAGS)	: Debug flags to pass to $(CXX).
+
+$(LD)			: The system linker (typically $(CC), but not
+			  necessarily).
+
+$(LDFLAGS)		: What to pass in to the linker, including -L arguments
+			  and other ld arguments, apart from -l library
+			  includes (see $(LDLIBS)).
+
+			  This should be done in the $(CC) args passing style
+			  when LD := $(CC), e.g. `-Wl,-foo', as opposed to
+			  `-foo'.
+
+$(LDLIBS)		: Libraries to pass to the linker (e.g. -lltp, etc).
+
+$(OPT_CFLAGS)		: Optimization flags to pass into the C compiler, -O2,
+			  etc. If you specify -O2 or higher, make sure that you
+			  also specify -fno-strict-aliasing, because of gcc
+			  fstrict-aliasing optimization bugs in the tree
+			  optimizer! Search for `fstrict-aliasing optimization
+			  bug'.
+
+			  Examples:
+			  1. tree-optimization/17510
+			  2. tree-optimization/39100
+
+			  Various bugs have occurred in the past due to buggy
+			  logic in the tree-optimization portion of the gcc
+			  compiler, from 3.3.x to 4.4, so far.
+
+$(OPT_CXXFLAGS)		: Optimization flags to pass to the C++ compiler.
+
+$(RANLIB)		: What to run after archiving a library.
+
+$(WCFLAGS)		: Warning flags to pass to $(CC), e.g. -Werror,
+			  -Wall, etc.
+
+$(WCXXFLAGS)		: Same as $(WCFLAGS), but for $(CXX).
+
+==============================
+Make System Variables
+==============================
+
+A series of variables are used within the make system that direct what actions
+need to be taken. Rather than me listing the variables here, please instead
+refer to the comments contained in `.../include/mk/master_rules.mk'.
+
+==============================
+Guidelines and Recommendations
+==============================
+
+Of course, the GNU Make manual is key to understanding the Make system, but
+here are the following sections and chapters I suggest reviewing:
+
+- implicit rules:
http://www.gnu.org/software/make/manual/make.html#Implicit-Rules
+- variables and expansion:
http://www.gnu.org/software/make/manual/make.html#Using-Variables
+- origin use: http://www.gnu.org/software/make/manual/make.html#Origin-Function
+- vpath use: http://www.gnu.org/software/make/manual/make.html#Directory-Search
+
+==============================
+Before Committing
+==============================
+
+One should rebuild from scratch before committing. Here's an example of how to
+do that:
+#!/bin/sh
+
+TOOLS_PATH=/path/to/tools
+
+# Replace [options] with any make specific options and variables, for each
+# step, example: -j 4, DESTDIR=/path/for/install, etc.
+make maintainer-clean [options]
+make \
+  ACLOCAL=$TOOLS_PATH/bin/aclocal \
+  AUTOCONF=$TOOLS_PATH/bin/autoconf \
+  AUTOHEADER=$TOOLS_PATH/bin/autoheader \
+  AUTOMAKE=$TOOLS_PATH/bin/automake \
+  autotools
+./configure [options]
+make all [options]
+make install [options]
+
+==============================
+Other Errata
+==============================
+
+- This system (in its current form) supports cross-compilation out of a single
+directory. Object directory support will be completed soon to properly enable
+cross-compilation. This is required to avoid sporadic Make-related errors.

+# generic_leaf_target

+# Generate a set of basic targets (all, clean, install) for a leaf directory
+# (no subdirectories).
+#
+# In order to properly emulate pre- and post- behavior, a pre-install and
+# _install target are generated as well. The flow for install is as follows:
+#
+# pre-install -> $(INSTALL_FILES) -> install
+#
+# Helpful variables are:
+#
+# $(MAKE_DEPS)			: What to execute before all.
+# $(MAKE_TARGETS)		: What to execute as direct dependencies of
+# 				  all.
+# 				  1. Defaults to the basename of the targets
+# 				     produced by the %.c -> % implicit pattern
+# 				     rules, e.g. the MAKE_TARGET in a directory
+# 				     like the following:
+#
+#				  $$ ls /bar
+# 				  foo.c
+#
+#				     Would be `foo'. Similarly, the following
+#				     dir structure:
+#
+#				  $$ ls /bar
+# 				  foo.c zanzibar.c
+#
+#				     Would be `foo zanzibar'.
+#
+#				  2. If you define MAKE_TARGETS as an empty
+#				     string, this will override the defaults.
+#				     I did this to avoid providing too much
+#				     rope to hang one's self in the event of
+#				     unwanted behavior.
+#
+# $(CLEAN_TARGETS)		: What targets should be cleaned (must be
+#				  real files). This will automatically append
+#				  adds the .o suffix to all files referenced
+#				  by $(MAKE_TARGETS)) to CLEAN_TARGETS, if
+#				  MAKE_TARGETS wasn't defined (see
+#				  $(MAKE_TARGETS)).
+# $(PREINSTALL_DEPS)		: What to run as direct dependencies of
+# 				  pre-install.
+# $(INSTALL_DEPS)		: What to run as direct dependencies of
+# 				  the _install target. These must be real
+# 				  files.
+# $(POSTINSTALL_DEPS)		: What to install direct dependencies of
+# 				  the install target.
+# $(INSTALL_MODE)		: What mode should we using when calling
+# 				  install(1)?
+#
+# If you choose to cherrypick the logic contained here, by changing around the
+# dependencies for $(INSTALL_DEPS) and $(POSTINSTALL_DEPS), then you must also
+# emulate the $(INSTALL_DEPS): pre-install and install: $(POSTINSTALL_DEPS)
+# dependencies, if you _use_ them.
+#
+# Also, if you wish to change the installation directory, from the set default
+# (testcases/bin) you must do something like either one of the following items:
+#
+# Method A:
+#
+# INSTALL_DIR			:= /path/to/installdir/from/$(DESTDIR)/$(prefix)
+#
+# e.g. if I wanted to install my binaries in testcases/bin, I would do:
+#
+# INSTALL_DIR			:= testcases/bin
+#
+# in my calling Makefile.
+#
+# Or Method B:
+#
+# INSTALL_DIR			:= /path/to/installdir/from/$(DESTDIR)
+#
+# e.g. if I wanted to install my binaries in $(libdir) (which may not exist
+# outside of $(prefix) right now, but could in the future), I could do the
