Comment:

 Not sure of this is worth keeping open.

 It may be possible to detect its availablity and print an error message
 during `make sdist` when its missing, but I'm not sure if the effort is
 worth it. Very few ghc devs actually do `make sdist` and those that do
 should remember than `lndir` is required.
