This commit improves the Python package infrastructure to allow Python
packages to be built with Python 3. The changes are fairly simple:
* Use either PYTHON_PATH or PYTHON3_PATH as the PYTHONPATH depending
on which Python is used.
* Depend on host-python or host-python3 and python or python3
depending on which Python is used.
