On some platforms, gcc generates library calls when __atomic_* functions are used, but does not link the required library (libatomic) automatically (supposedly to allow the app to use some other atomics implementation?). Detect this at configure time and add the library when needed. Tested on armel (library was added) and on x86_64 (was not, as expected). Some documentation on this is provided in GCC wiki: https://gcc.gnu.org/wiki/Atomic/GCCMM Fixes: 8915f0c0 "util: use GCC atomic intrinsics with explicit memory model" Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=102573 Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Reviewed-by: Matt Turner <mattst88@gmail.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com>
