Nightly builds of GHC HEAD for Ubuntu 12.04.2 LTS

Chatting with merijn on #haskell, I realized I have a file server running Ubuntu in a VM that’s idle most of the time, so I decided to set up a jenkins user there and make use of it as a build slave in the evenings. This means that at http://ghc.newartisans.com, you’ll now find nightly builds of GHC HEAD for Ubuntu as well (64-bit). It also includes fulltest and nofib results for each build.
