    The Python interpreter needs a filesystem where to keep its libraries. This
    patch creates a Python virtual environment and installs the Python 3 
standard
    library in /lib/python3.7 directory. For creating the filesystem the 
following
    command has to be run:
    
    $ make python-rootfs path=<directory>
