  * Do not pass Maybe LocalBuildInfo to clean hook
  It is a bad idea for clean to do anything different depending
  on whether the package was configured already or not. The
  actual cleaning code did not use the LocalBuildInfo so this
  only changes in the UserHooks interface. No Setup.hs scripts
  actually make of this parameter for the clean hook.
  Part of ticket #133.
