This patch causes qemu-system-ppc to fail to load ppc44x_defconfig:

$ make -skj"$(nproc)" ARCH=powerpc CROSS_COMPILE=powerpc-linux- O=out/ppc distclean ppc44x_defconfig zImage

$ timeout --foreground 30s unbuffer \
qemu-system-ppc \
-machine bamboo \
-no-reboot \
-append "console=ttyS0" \
-display none \
-initrd ../../cbl/github/boot-utils/images/ppc32/rootfs.cpio \
-kernel out/ppc/arch/powerpc/boot/zImage \
-m 128m \
-nodefaults \
-serial mon:stdio
qemu-system-ppc: could not load kernel 'out/ppc/arch/powerpc/boot/zImage'

$ ls out/ppc/arch/powerpc/boot/zImage
out/ppc/arch/powerpc/boot/zImage

Is this expected? Is there some other config or machine that we should
be testing instead?

Cheers,
Nathan
