[pulseaudio-discuss] [PATCH 0/4] Build fixes

[poljar (Damir Jelić)]

I finally got annoyed enough by multiple warnings from Autoconf and 
Automake to fix them.

The first patch explicitly enables the subdir-objects option. This option
has been supported by automake for over a decade:
    http://git.savannah.gnu.org/cgit/automake.git/commit/?id=88b595974744cad79fa4bc2492a796c6037eea49

The next 2 patches add brackets around AC_LANG_PROGRAM and avoid the same
warning. This is kept in separate commits because one of the files is from
an external source but I couldn't find an updated version of it. Squash
them if needed.

This warning is the result of an change in autoconf 2.68:
    The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and
    AC_RUN_IFELSE now warn if the first argument failed to use
    AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file
    contents.

The last patch updates the ax_pthread.m4 file from the GNU Autoconf Archive
tarball and avoids the same warning as the last two patches.
