output error code when xmonad.hs compile fails without any error output
Ignore-this: 6249588a9d427a49fceb99d78a95c438
Currently if there is no ghc on the path say for some reason,
xmonad.error is empty. This patch makes
it output the exitcode code when the compile process fails
without any error output. (It might be easier just to spawn
a shell to get "ghc: command not found" output for free.)
