 156         (tc_gen_reloc): Remove relaxation handling.
 157         (md_convert_frag): Go through the fixups for a relaxable macro and
 158         mark those that belong to the unneeded alternative as done.  If the
 159         second alternative is needed, adjust the fixup addresses to account
 160         for the deleted first alternative.
