Yes.  GtkAda for example.

Is that not already the case?

  if (!get_elf_backend_data (abfd)->can_gc_sections
      || info->relocatable
      || info->emitrelocations
      || !is_elf_hash_table (info->hash))
    {
      (*_bfd_error_handler)(_("Warning: gc-sections option ignored"));
      return TRUE;
    }
