Ahh.. Well, that would be more of a linker relocation ABI change, not
really a run-time ABI change. And as it needs a new relocation type
anyway, because of the overflow case (I assume the current .rel20
complains loudly when it overflows, right?), this should be ok.
And the code to jump over ldgp obviously exists already if there's a
"-relax" linker option.
