[PATCH 13/25] autofs-5.0.7 - use LIBS for link libraries

[Ian Kent <raven@themaw.net>]

From: Lan Yixun (dlan) <dennis.yxun@gmail.com>

quote:
 "Don't use this variable to pass library names (-l) to the linker; use LIBS instead."

see the section "Variable: LDFLAGS" in:
http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/PreseOutput-Variables.html#Preset-Output-Variables

Edited by: Ian Kent <raven@themaw.net>
The variable usage changes for LDFLAGS and LIBS appear to be dependent
on each other so merge them to try and avoid breakage if not all are
used by someone. I also had changed the patch titles slightly when I
imported them but they should be easily recognisable.
- merge patches
  - pthread-link-library-should-be-put-into-LIBS-not-LDFLAGS
  - library-should-be-passed-via-variable-LIBS-not-LDFLAGS
  - accumulate-LIBS-variable-changes-otherwise-we-may-lose-early-settings
  - allow-user-to-pass-LDFLAGS-via-configure
- add LIBS to build rules, might fix DMALLOC build problem
