#1290: 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.
