--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
FWIW, x86 has

  /* Reference count of C/C++ function pointer relocations in read-write
     section which can be resolved at run-time.  */
  bfd_signed_vma func_pointer_refcount;

and

  /* Don't create the PLT entry if there are only function pointer
     relocations which can be resolved at run-time.  */
  else if (htab->elf.dynamic_sections_created
           && (h->plt.refcount > eh->func_pointer_refcount
               || eh->plt_got.refcount > 0))
    {
