mesa: Add define to indicate missing 64bit atomics on armv5

This is wrongly detected by configure since it only checks for
__sync_add_and_fetch and not __atomic_fetch_add, it decides
to let compiler emit references to atomic functions which
it expects to be provided by libgcc, but thats not the
case for armv5 arch
