  * Workaround the fact that haddock stomps on our precious .hi and .o files
  When using "haddock --optghc-XTemplateHaskell" haddock will write out .o
  and .hi files. This is bad because it replaces the ones we previously
  built. This results in broken packages later on. Of course haddock
  should not do this, it should write temp files elsewhere. The workaround
  is to tell haddock to write the files to a temp dir.
