Making the population of xen/ depend on the time stamps of a subset of
the headers put there is error prone. The creation of a few dozen
symlinks doesn't take a meaningful amount of time (compared to the
overall building of tools/), and hence - to be on the safe side - should
simply be done always. Convert the goal to a phony one and drop its
dependencies, effectively taking further what 8d8d7d6b3dc1 ("tools: fix
linking hypervisor includes to tools include directory") had already
