This is generally fine for the purpose of compile testing, but of course it means that the kernel is not usable on actual hardware, and it causes a warning about this fact. As most of the build bots now force-enable CONFIG_COMPILE_TEST for randconfig builds, use that as a guard to control whether we warn on this type of broken configuration. We could do the same for the missing-cpu-type warning, but those configurations fail to build much earlier.
