structured-haskell-mode: link Haskell libraries statically into this executable

Browse Source 
It's my understanding that Emacs runs the "structured-haskell-mode" binary
virtually every time you press a key in an Haskell buffer, and since
dynamically linked Haskell binaries take *much* longer to start up, switching
this particular package to statically linked libraries ought to result in a
performance boost.
