    tools/x86: don't rebuild cpuid-autogen.h every time
    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: eddf9559c977 ("libx86: generate cpuid-autogen.h in the libx86 
include dir")
