emulation/qemu-power8: initial mainboard and arch commit

This builds and produces an image.

The next step is to get a 'halt' instruction into the boot block and then attach with qemu.

I can't get the powerpc64le-linux-gnu-ld.bfd to recognize any output arch but
powerpc. That makes no sense to me.
