libglib2: add patch to rework clock_gettime() test
The test for clock_gettime() in configure.in doesn't work properly when a previous package has loaded the shared configuration cache with informations about the availability of clock_gettime. A package such as ctorrent does so, which means that compiling ctorrent *then* libglib2 currently fails. According to people on the Autoconf mailing list, the libglib2 test is likely the one that needs to be fixed. The problem is that the AC_CHECK_FUNCS() test assumes that if it finds clock_gettime() it means that there's no need to add any -lrt flag to the build. Unfortunately, due to the shared configuration cache, this test is already done with -lrt, so the test succeeds, and libglib2 does not know that it needs to add -lrt to G_THREAD_LIBS and G_THREAD_LIBS_FOR_GTHREAD. So instead, we remplace the test with an AC_SEARCH_LIBS() test, followed by a test on the result of this AC_SEARCH_LIBS() test to add the necessary -lrt to G_THREAD_LIBS and G_THREAD_LIBS_FOR_GTHREAD. Therefore, even if the result for the AC_SEARCH_LIBS() test is cached due to the prior execution ctorrent ./configure script, libglib2 ./configure will properly add -lrt to the appropriate variables. Obviously, as this patch modifies the configure.in file, we enable the autoreconf step for the libglib2 package. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
