Does static pie (ET_DYN with non-fixed load address, _DYNAMIC
relocations, but no PT_INTERP, DT_NEEDEDs, or symbolic relocations)
currently work with gold? If so, what is the way to request it? I
would say it would make sense to try to do things the same, but from
what you're saying it sounds like gold already significantly
mismatches the bfd linker behavior...?
