add -fspec-constr-count workaround

Browse source 
ghc 7 produces these warnings http://hackage.haskell.org/trac/ghc/ticket/4288

there to avoid specialization blowing up binary size. Perhaps that default
is a little low? I needed 4 to avoid a warning on Unused.hs, and 5 to avoid
warnings on test.hs
