Distutils doesn't support mingw. Why not use setuptools? (just never mind I didn't read things fully)

I don't know why pip uses this, but it still does (that version of pip was installed by installing the python package, then executing python -m ensurepip (per python's 3.x docs).

There's a patch here for distutils already, so I assume MSYS2 supports it - see related PR which handles this issue better.
