    stubdom: xenlibs linkfarm, ignore non-regular files
    
    When we will convert tools/ build system, their will be a need to
    replace some use of "vpath". This will done making symbolic links.
    Those symlinks are not wanted by stubdom build system when making a
    linkfarm for the Xen libraries. To avoid them, we will use `find`
    instead of plain shell globbing.
    
    For example, there will be a link to "xen/lib/x86/cpuid.o" in
    "tools/libs/guest/".
