And these or their directories are not symlinked from somewhere else?

I'm asking because the current code on the branch looks for the
native-lisp directory relatively to the directory of the .pdmp file,
so if Emacs picks up the .pdmp file from some unexpected directory,
perhaps via a symlink, it could decide to look for native-lisp in the
wrong place.
