--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Comes from:
  if (p->target_binary != target_option_current_node)
    {
      (void) targetm.target_option.pragma_parse (NULL_TREE, p->target_binary);
      target_option_current_node = p->target_binary;
    }


The front-end expects the target always to implement these target hooks it
seems rather than the default.

Really I think the arm back-end should implement them so that thumb2 code can
be in the same source file as arm32 code and would help out LTO when people mix
and match them.
