Obviously this includes deleting xen/lib/x86/*autogen.h. As a result there's no original version for $(move-if-changed ...) to compare against, and hence the file and all its consumers would get rebuilt every time. Introduce a "prep-y" rule to move xen/lib/x86/ on the side, to then recover any *autogen.h from there prior to invoking the respective recursive $(MAKE) invocation.
