--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Oh it is because -msmall-data-limit defaults to 8.

And default_use_anchors_for_symbol_p returns false for small data sections:
  /* Don't use anchors for small data sections.  The small data register
     acts as an anchor for such sections.  */
  if (sect->common.flags & SECTION_SMALL)
    return false;

But there is no small data register ...
