 161         (tc_gen_reloc): Remove relaxation handling.
 162         (md_convert_frag): Go through the fixups for a relaxable macro and
 163         mark those that belong to the unneeded alternative as done.  If the
 164         second alternative is needed, adjust the fixup addresses to account
 165         for the deleted first alternative.
