GHC head and .haddocks

[Edsko de Vries]

Ok, I just realized that that ~/local/lib/ghc-7.7.20130721/html
directory it is looking for *does* exist in a normal build and
contains themes and stuff. Copying that from inplace/lib/html in the
ghc source tree avoids the internal error message, so this is probably
just another manifestation of the failure to install the haddocks in
the first place. I still don't know why that happened though (why it
didn't build the .haddock files nor install them, or the
inplace/lib/html directory).
