ninja depends on python3 specifically, but the configure.py file
simply uses "env python". Where no python is selected for the target
you simply won't get a python symlink in $(HOST_DIR)/usr/bin, so the
configure.py script fails to run since it can't find "python".
Notice that in order to reproduce the issue, you must not have
python2 installed on your host machine.
