Well, looking at some finally dead hacks, ....

int
remote_Z_write_wp_packet_supported_p (void)
{
   struct remote_state *rs = get_remote_state ();
   /* Don't even think about it if the remote target isn't selected.  */
   /* FIXME: cagney/2002-05-19: This shouldn't be necessary - the
      WATCHPOINT methods should be in the target vector.  Ulgh!  */
   if (target_shortname == NULL
       || strcmp (target_shortname, "remote") != 0)
     return 0;

notice that the problem it was trying to avoid was with ``target sim''. 
  So in the above the question is no longer local/remote but local VS 
remote VS sim VS ....
