This is different from what I have been doing. I have been using the
software collection for python3. The software collections do not change the
base environment and you have to explicitly switch to them. I do this when
working on the documentation.

scl enable rh-python36 bash

I installed python3. I now have this for tab-completion for python:

$ python
python            python2.7         python2-config    python3.6
python-config
python2           python2.7-config  python3           python3.6m
 python_count

Will the RTEMS Python code pick the Python3 automatically?

FWIW I think the qemu RSB script already needs Python3. I have had to
use the software collection version to build it for the past few months.

Whatever the answer is, we need to update the manual if we are
heading to a change in expectations.
