OK thanks!

I was scratching my head over this exlanation, until I figured that
the difference is caused by the XCOFF ppc_fix_adjustable(). So the
bug was that when I moved the fixup handling code in md_assemble() to
md_apply_fix(), I failed to take into account the intervening action
of ppc_fix_adjustable() in changing XMC_TC symbols to XMC_TC0 plus an
offset.
