Hard links will only work on the same filesystem, which is not necessarily the
case for all MacPorts installations. Additionally, they also link file metadata,
and thus the restricted flag.

Mounts are a nice idea, but not possible without root privileges, and that leaves
out everybody that uses a user-only installation of MacPorts. So this could only
be done as an optimization, and I'm not sure it's worth it then. Cache
invalidation would definitely be easier with it, though…
