Hi Ross,

Thanks for the review, please see more comments:
The glib-2.0-native had already depend on python-native before this patch,
the depends chain is:

glib-2.0-native -> python-argparse-native -> python-native

I inherit the glib-2.0-native is for using the ${PYTHON} variable, it doesn't
change its depends, since we had built python-native already, and it works,
it seems more reasonable to use it rather than show error message and let the
user install other pkgs on the host, I think that this is what our native
recipe for.

// Robert
