 I believe that ghci libraries files (HS*.o) are now redundant (and Cabal
 no longer builds them at least in trunk) so I think it would be good to
 stop ghc building them also now.

 I didn't try hard but didn't work out yet how to do this in the ghc build
 system - patching Cabal didn't seem to be sufficient.
