runghc has a -f option which allows to specify the path to GHC. However,
it uses `rawSystem` and if the path is incorrect, we only get a nonzero
exit code. For example, attempting to use "ghc -fdefer-type-errors X.hs"
gives absolutely no output.
Attached patch uses `findExecutable` and gives an error message if the
executable is not found. This is not the ideal solution, but I think it's
better than the current state.
