Summary: add linux-patch Makefile target

the patch below, together with the attached script, add a
Makefile target called "linux-patch", which automatically
generates a kernel patch that can be applied to a vanilla
Linux kernel tree to add Xen.

This is useful for people who want to add Xen to the kernel
package of a Linux distribution.
