Quick hack to build SMT LLVM style.

 - I don't want to make proper bison/flex rules, and eventually I think we
   should just check in the generated files since we don't expect them to
   change, so for now just build the files in the src directory. Eventually we
   will want to disable these rules so that it works for people who don't have
   bison/flex.
