Comment:
Yes, although we don't specifically tell Meson anything about python. The build system sets, in the environment,

```sh
PYTHONPATH=${XBPS_CROSS_BASE}/${py3_lib}
PYTHON_CONFIG=${XBPS_CROSS_BASE}/usr/bin/python3-config
```

and `$_PYTHON_SYSCONFIGDATA_NAME` to the appropriate name for the cross host. Thus, running the build python *should* return parameters for the target.
