    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
