I'd like to have a full setup so I can do run testing as well.

I was thinking of running a ppc distro on qemu, and building and running 
kvm-ppc on that to test.  Even if  I don't run it, it's a much better 
build-time environment.  Of course running the unit tests and an image 
or two will be even better.

So, at best, I'd like an emulation environment that allows me to build 
and run; at worst, build only.
