Users can pass ARCH=3Dpowerpc or ARCH=3Dppc to test 32-bit PowerPC. The default qemu-system-ppc g3beige machine [1] is used to run 32-bit powerpc kernel. The pmac32_defconfig is used with extra PMACZILOG console options to enable normal print. Note, zImage doesn't boot due to "qemu-system-ppc: Some ROM regions are overlapping" error, so, vmlinux is used instead.
