I have finally applied to next, with one change. See below.

I replaced this with:

	$(if $(BR2_PACKAGE_PYTHON3),host-python3,host-python)

which is something we do in many other packages, to use host-python3
when host-python3 is anyway going to be built as a dependency of the
target python3.

I tested it, and it does seem to work, i.e I was able to use the
binding generator tool with a Python 3 installation.

Thanks!
