- First pass at getting the powerpc ports to compile

The static device tree is not built properly at all yet, but at least we get through it.
  FIXME (What is the proper way to handle add in boards?)
- Add generic div64 support and ppc div64 support
- Fix abuild so it properly generates the CC line when cross compiling.
- Add one more possible ppc cross compiler target
