On openSUSE Leap 42.1, using system with both python2- and
python3-config, qmake selects python3.

qmake
Project MESSAGE: Building for QT4...
Project MESSAGE: Building for Linux/Mac...
Project MESSAGE: Using /usr/bin/python3-config
Project MESSAGE: Python3 detected.

Is this a deliberate choice, determined by my system or random? I am
accustomed to seeing a default to python2, but if python3 works then not
a problem.
I still am not able to tell if the runtime situation is up due to
another error (Type str doesn't support the buffer API) which is still
under investigation.
