No, this is wrong. The python3-config should come from the Python we use to build stuff for the target, so host-python/python. We do some hacky stuff to combine the host-python binary with target python stuff to get a cross python to build stuff. Maybe that needs to be extended so that libgpiod will find python3-config?
