So this ppc32 is indeed spreading everywhere :(

That is potentially going to require a whole bunch of changes in our 
makefiles, source file renaming and possibly even build file changes. 
This will take time to investigate.

It would have been simpler to simply let ppc imply 32-bit and use ppc64 
as needed to distinguish. Our LIBARCH for this is likely to remain ppc 
not change to ppc32
