Issue:
Currently my FreeBSD build fails due to inclusion of a file
that does not exist on FreeBSD. Next to the fact that I'm not
really certain that everything will build and run on PPC with
FreeBSD. :)

Perhaps we can conditionalise PPC code just as we did with ARM code?
Or perhaps even exclude pp.cc in CMakeLists.txt without upsetting the
balance of order.
