Bug#711581: Ubuntu packages on Launchpad

[Bernhard Reiter <ockham@raz.or.at>]

There has been some disucssion [1] on the Darling mailing list regarding
Ubuntu packages for darling and its GNUstep dependencies, and someone
seems to have begun implementing them [2, 3] which he claims to be
functional, so maybe that could be used as a start.
