Doesn't whether to adjust also depend on relocation type? For example, the
very first thing checked on x86 is

  /* Don't adjust pc-relative references to merge sections in 64-bit
     mode.  */
  if (use_rela_relocations
      && (S_GET_SEGMENT (fixP->fx_addsy)->flags & SEC_MERGE) != 0
      && fixP->fx_pcrel)
    return 0;
