Maybe define a variable for it. Do you know how this stuff works?

There is one PowerPC config in OSELAS.Toolchain. That is built with '--with-cpu=603e --disable-altivec'... I've not used any PowerPC hardware personally in over a decade. So the toolchain never changed either. I'm mostly using this stuff for more test coverage. I'd be happy to merge PPC64 support for PTXdist.
