Some makefile fixes for the Interpreter:

- Make the generation of LLDBWrapPython.cpp respect the VERBOSE setting.
- Use -classic mode when generating. LLDPWrapPython.cpp #errors out if -classic
  wasn't set when it was generated with recent Swig.
- Install the Python modules. Now we shouldn't get loads of Python errors
  trying to run LLDB.

Last of my build fixes. The LLDB that I built works, except that I can't debug
anything with it until debugserver gets built.
