+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.
