Damn, yes, overlooked it.
Here is a new patch. Retested as well.
This shouldn't effect the linux-ppc platform.
I'll look at that next.

Based on a patch from Vladimir Makarov <vmakarov@redhat.com>:
* config/rs6000/tm-rs6000.h (STAB_REG_TO_REGNUM): Delete it.
It is now multiarched.
* rs6000-tdep.c (rs6000_stab_reg_to_regnum): New function.
(rs6000_gdbarch_init): Set gdbarch_stab_to_regnum.
