I think this needs to be a `python` from `inputs` rather than 
`native-inputs`, for cross-compilation, IIUC.

I tried building node 14.18.0, and it ran into other issues, but there 
were still a number shebangs with `python` rather than `python3` in 
various places, though I think they'd be fine with `python-wrapper`.
