That means basically moving the host Python from $(STAGING_DIR_HOST)
to $(STAGING_DIR_HOST)/usr and making the PYTHONPATH var
as an argument.

Some python packages (e.g. cffi) compile one or more shared libraries
as part of their setup process. When these packages are setup
dependencies of other packages (e.g. cryptography), these packages (and
their shared libraries) will need to be loaded on the host system.

This adds a makefile, similar to python-package.mk, to simplify
installing python packages on the host.
