Touch Haskell programs after ghc --makeing them.

Browse Source 
If GHC didn't need to do anything (e.g. you've touched one of the source
files but not changed the contents), it doesn't update the output file
-- so next time you run make, it thinks it needs to run the rule again.
Touching the output matches make's expectation of what a compiler should
do.
