The first thing the "xen-dir" rule does is delete the entire xen/
subtree. 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. Instead only find and delete all the symlinks.
Fixes: eddf9559c9 ("libx86: generate cpuid-autogen.h in the libx86 include dir")
