Ok, that gets me closer. I now get three package-test failing (out of
60):

  GhcPkgGuess/Symlink:                 FAIL

These test don't fail when I'm building with ghc-7.10 (which was also used to
build GHC). Should these tests fail like that?

Maybe I should build cabal twice, once with ghc-7.8 to make sure it builds
and once with ghc-7.10 where I can run the tests as well.
