6.0.0a -Fails to build on my powerpc box (debian wheezy)

With Richard Biener's analysis this was easy to fix:

We might want to improve GMP's config.guess to better recognise the
affected CPUs.  We have very broad testing for powerpc64, but no system
was identified as a plain powerpc64-*.

I am curious about the contents of /prec/cpuinfo for the problem systems.
