that works -- except maturin doesn't get told what python's argv[0] is -- the
error message for `pip install .` showed the entire list of arguments passed to
maturin:
['maturin', 'pep517', 'write-dist-info', '--metadata-directory',
'/tmp/pip-modern-metadata-60u_5apa', '--bindings=pyo3',
'--cargo-extra-args=--features python-extension']
