        (_bfd_elf_allocate_ifunc_dyn_relocs): Updated.  Replace
        "shared object" with "PIC object" in comments.  Avoid PLT if

        Make room for the special first entry in PLT and allocate PLT
        entry only for PLT and PC-relative references.  Store dynamic
        GOT relocations in .rel[a].iplt section for static executables.
        If PLT isn't used, always use GOT for symbol value.  Don't
        allocate GOT entry if it isn't used.
