patch applied (cabal): Remove some now-unecessary cleaning that causes problems for haskell-src

Thu Sep 20 13:32:57 PDT 2007 Ian Lynagh * Remove some now-unecessary cleaning that causes problems for haskell-src The code that removes .hs files in the source tree generated from .y files had a comment: XXX: This is actually no longer necessary, but we keep it, so that clean works correctly on packages built with an older version of Cabal This was causing problems for source distributions that include such generated files (including haskell-src in extralibs).
