There is still something I haven't got right: if you do make -j3, it
does this sort of thing:

  GZIP    arch/powerpc/boot/kernel-vmlinux.strip.gz

make[2]: *** [arch/powerpc/boot/kernel-vmlinux.strip.o] Error 1

I have no idea why it tries to make those things twice in parallel.
It doesn't do that for vmlinux.

I think this comes from the targets evaluation. Maybe strip needs to be
some sort of serialization:

cmd_stripvm = $(STRIP) -s -R .comment $< -o $@.$$$$ && mv -v $@.$$$$ $@

gzip is also called twice, use the mygzip rule from
arch/ppc/boot/images/Makefile
