Might well do (and a bunch of the other parametrization flags in there
that look like they might even date from when the ISA was up in the
air), but I doubt it would fix the issue. aarch64-branch-relax looks
very suspiciously like it would be at the beginning of any
alphabetical sort of options.

I suspect there's some weird DLL name resolution thing going on and
Kai would just hit the next option if it was removed, but don't really
know what (particularly on Windows).
