Are there actually architectures hat _don't_ support those relative
32-bit relocations? That really feels pretty fundamental.

I would have expected all of them to do it - is your selection of
arm64/powerpc/x86 perhaps more about "I have tested these" than about
anything else?

Because I'd almost prefer to just do the switch-over unconditionally
if that is at all possible?
