Bug 856404 - Don't default HOST_* variables to target ones when cross compiling. r=ted

# High Priority

- Figure out the script story on the various platforms. On Windows, look into
  the launcher thing that effbot has. Unix, don't install the script my
  default. They can always do "python -m which ..." with Python >= 2.4.
  Suggest an alias that some folks might want to use for that.


# Medium Priority

- define __all__?
- improve test suite
- test with other versions of Python
- get the PATHEXT attached extension to reflect the actual canonical
  case of file matches on Windows, currently the extension from PATHEXT
  is always uppercase
- What to do with Change 145624 by shanec. It is a bit of a
  bastardization. Maybe allow this with a special option to allow the change
  in semantics.

# Low Priority

- have a version for pre-generators (i.e. Python 2.1)
- add a "logging" interface
