GHC 7.8.1: Many haddock-related complaints from 'ghc-pkg check'

[Conal Elliott]

Thanks, Austin & Herbert.

Switching from clang to gcc-4.8 and reinstalling libraries eliminated most
of the noise for me.

In one set of my own libraries (bringing in new dependencies), I did get
several more haddock warnings from 'ghc-pkg check'. I reinstalled each of
those libs explicitly (cabal install --reinstall --force-reinstalls),
ignored the resulting warnings, and now back to a clean `ghc-pkg check`,
and (so far) working packages.
