I'm not sure. On my machine:

$ python3
Python 3.6.8 (default, Jan  3 2019, 03:42:36)
[GCC 8.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
\>>> import distutils.sysconfig
\>>> distutils.sysconfig.get_python_lib(True, False)
\>>> distutils.sysconfig.get_python_lib(True, False, '')
\>>> distutils.sysconfig.get_python_lib(True, False, '/src/lib')
