For me trying powerpc64-xtoolchain-gcc was just an initial experiment for
personal interest, even though if I used it I'd be cross building back to
powerpc64 with the modern gcc for now. No grand disaster for me if building it
does not work for a while.
But finding the issues and reporting
I tried to portmaster devel/powerpc64-xtoolchain-gcc but it failed during the
building of powerpc64-gcc with the build reporting 5 missing files, 4 of which
seemed to be different file names used in some places compared to others and
one file apparently built but was not put under
