[RFC/PATCHSET 00/30] perf tools: New build framework

hi,
I'm following up on latest post from Alexis:
http://marc.info/?l=linux-kernel&m=141427580405357&w=2

Since it's actually small portion of kbuild that perf needs,
I realized it's actually better to steal it than 'reconfigure'
kbuild to be usable for perf.

Also this patchset is kind of incremental version of the latest:
perf tools: Add kbuild support into Makefile.kbuild
so it should be easier to review.

NOTE I couldn't find any copyright/credit messages in the kbuild
system, but would be happy to include it if someone suggests one.

The stolen parts are in files:
Makefile.kbuild
Build.include

The idea and more details are explained in the 'Documentation/Build'
file. The basic idea is the same as in kbuild system, with some minor
changes to allow for multiple binaries build definitions.

User provides 'Build' files with objects definitions like:
perf-y += perf.o
perf-y += builtin-bench.o
...

libperf-y += util/
...

and the build framework outputs files:
perf-in.o
libperf-in.o

which are then linked into appropriate binaries/libraries.
(perf libperf.a libperf-gtk.so)

This patchset does not include the user configuration changes
support (which is the ultimate goal), but last 2 patches shows
how easy it's now to disable some parts of the perf code:
perf tools: Add support to configure builtin commands inclusion
perf tools: Disable test code

Also now we have the full dependency check ((gcc -Wp,-MD,... stuff) and
build command line is stored/checked automatically by the build system.

The patchset is also available in:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/build

All tests/make tests pass. I tested only x86_64 arch.. any
feedback from other archs would be great ;-)

thanks for comments,
jirka
