haddock issue building ghc-7.8 from git

[Austin Seipp]

You need to say:

$ git clone -b ghc-7.8 https://git.haskell.org/ghc ghc-7.8
$ cd ghc-7.8
$ ./sync-all -b ghc-7.8

That should do the trick and get you a clean, working repository
(sync-all is fiddly with checkout at the moment, if I remember
correctly).
