if head magic is missing or wrong unexpectedly, we'd
better to reject booting.
e.g.
I make a mistake to boot a vmlinuz for MIPS(which
I think it's for x86) like this:
qemu-system-x86_64 -kernel vmlinuz -initrd demord
then qemu report:
"qemu: linux kernel too old to load a ram disk"
that's misleading.
