build: Fix distclean when repo location changes

If the path to xen-unstable.hg changes (i.e. you move the repo), the symlinks
inside xen-unstable.hg/stubdom/libxc-x86_[32|64]/ all become broken, which
breaks distclean because make attempts to clean inside those first and fails to
find Makefile (which is also a symlink).
