Attempt static scheduling, fall back to dynamic if fatal error

Also fix up the scala examples Makefile a bit

I like the changes to the Makefile (and .gitignore) but I have two reservations about the changes to the code:

1. They use global variableles and a strange recursive structure to handle arguments.
2. This way, any error in static schedule leads to dynamic scheduling. My idea was that for tree languages etc, static scheduling isn't necessary (there's nothing to schedule) and this shouldn't be an error, but rather we should use dynamic scheduler, not because of dynamic scheduling per se, but because the implementation is more complete.

Yeah, I don't love the goofy recursive structure either, but in my limited C knowledge I believe it's the only way to swallow an abort.

But okay, sounds good, I'll refactor to not swallow all fatal errors and instead handle just this case.
