ghc runs preprocessor too much

When an external preprocessor has been specified with -F -pgmF, and then using ghc --make, ghc runs the preprocessor on every .hs file, even those for which compilation is skipped. This seem unnecessary and it slows down recompilation significantly when you have many files.
