I suspect, perhaps for reasons to support your other tools on the
system, the environment variable PYTHON is set, pointing to a python2
binary.  Try 'PYTHON= ./configure' and see if you get further, where it
will instead use the default python3 from the waf 'shebang'
(#!/usr/bin/env python3)

You will need to use 'PYTHON= make -j' as well
