I'm *very* confused. You're doing ifneq here but you're talking about
it as if you are *adding* them for Clang, also these options are already
added elsewhere (lines 57, 64, 86, 89) so why add them here?
Because when David Woodhouse's recent .code16 changes made it upstream (which invalidated most of our original patch) it seems I didn't remove this properly from our patch as well. :)

Thanks David for your patches. Thanks Peter for your sharp eyes!

Another example of why reviewing code on the mailing list works so well.

I will fix and resend.
