I know it is the easiest quick fix, but it's not the long-term proper solution. Instead, I've started looking at all architectures, to see which of the __sync_*() and __atomic_*() builtins are supported, when -latomic is needed or not needed, etc. Once we have this picture, we can then design how such dependencies should be expressed rather than adding more and more architecture exclusions.
