Alter makefiles to accomodate the new powerpc arch and forget the old ppc and ppc64 ones. This is based on guesswork and will probably need some clean(s)ing up by somebody more knowledgeable on the Xenomai makefile system. The problem is that the makefiles need to map three kernel archs (ppc,ppc64 and the future powerpc) to one xenomai arch (powerpc).
