This makes distutils link against python3 instead of python3.x when py_limited_api is set on the extension. With MSVC this is solved via pragma, which doesn't have an alternative with our toolchains. This depends on libpython3.dll being installed, so https://github.com/msys2-contrib/cpython-mingw/pull/148
