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. Kernel uses ARCH=powerpc for both 32-bit and 64-bit PowerPC, here adds a ppc variant for 32-bit PowerPC and use it as the default variant of powerpc architecture. Users can pass ARCH=powerpc or ARCH=ppc to test 32-bit PowerPC.
