Note that at least right now, __int128 is marked as conditional for arm64:

        select ARCH_SUPPORTS_INT128 if CC_HAS_INT128

which implies that we may have compiler versions that don't actually
support it at all.

That said, I'm not sure what those compiler versions might be. Maybe
this is historical copy-and-paste noise.
