Should there be a note or something about waf needing python and we recommend

I think this belongs to the Host Computer section. The quick start uses the
RSB, so if you managed to build the tools, you must have a working Python.
The RSB uses Python and the RTEMS Tools use waf.
The RSB can use python2 or python3 without a python. What about a note to say
... "Waf uses python and you need to make this command available on your
system".
Now I am a bit confused. I thought every UNIX-like system provides a
#!/usr/bin/env python
which maps to Python 2 or 3?
Apparently on some distros the python executable is not automatically installed
with a suitable python2 or python3. I am not aware of the specifics of this but
it was raised as an issue that I fixed in the RSB:
https://devel.rtems.org/ticket/3537
I have never seen a system in which
#!/usr/bin/env python2
or
#!/usr/bin/env python3
works, but not
#!/usr/bin/env python
How many Python scripts would stop to work in this case? However, the
availability of a python command is not mandatory according to:
https://www.python.org/dev/peps/pep-0394/
I think we should note in the "Host Computer" section that a "python"
command is mandatory for RTEMS and remove the RSB extra stuff.
