It's probably not that hard to support bi-arch in powerpc gas.  I just
haven't got around to it.  And yes, you can solve the problem by
configuring powerpc-linux tools to support powerpc64 and a partial
install of powerpc64-linux tools, ie. everything but ld.

I'm talking about situations where one of the tools does things
differently for the default target.  See bfd/format.c
bfd_check_format_matches

	  /* If this is the default target, accept it, even if other
	     targets might match.  People who want those other targets
	     have to set the GNUTARGET variable.  */
	  if (temp == bfd_default_vector[0])

I'm not worried about the tools coping.  I'm worried that package
Makefiles will need modifying to specify an explicit bfd target.
