libgit2 is currently a library without any reverse dependencies so the
missing atomic symbols do not cause build failures yet.
libgit2 uses the atomics intrinsics on gcc >= 4.7 and the sync
intrinsics on previous gcc versions. Since gcc 4.9 is the new
minimum, ignore the sync intrinsics requirements.
The next version of libgit2 will also build a binary, which will
expose the problem.
