Right, Fabian installed its code already, but I found out at that point
that the way it works (i.e copying files from emacs.git) is problematic
in various ways: it should instead setup symlinks.

Yes, it kinda works but it suffers from various warts (e.g. "make
externals; make" will always recompile all the :core packages).

No, we should change to code to use symlinks instead of
file-copies first (and at the same time change it as I suggested,
i.e. to only delete symlinks and empty directories).
