kbuild: fix make rpm for powerpc
Mike Wolf authored

The default target for most powerpc platforms is zImage.  The
zImage however is in arch/powerpc/boot and the mkspec script
was set up to get the kernel from the top level of the kernel
tree.  This patch copies vmlinux to arch/powerpc/boot and then
copies the kernel to the tmp directory so the rpm can be made.
