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?
For example with my upgrade to FreeBSD 12.1 Python changed to 3
automatically:
$ /usr/bin/env python
Python 3.6.9 (default, Oct 24 2019, 01:18:01)
[GCC 4.2.1 Compatible FreeBSD Clang 6.0.1 (tags/RELEASE_601/final
335540)] on freebsd12
Type "help", "copyright", "credits" or "license" for more information.
>>>
$ ls -l /usr/local/bin/python
lrwxr-xr-x 1 root wheel 7 Oct 25 17:32 /usr/local/bin/python -> python3
The "waf" in rtems-tools uses
$ head -n 1 waf
#!/usr/bin/env python
It seems this extra logic in the RSB is a unnecessary at least for the
RTEMS Tools.
I will add a sentence about Python.
How would a user adjust a BSP setting, for example the optimisation to -O1 to
debug? A simple example would be nice. I see cannot see how as there is nothing
in the INI file except building the tests.
This is too detailed for the quick start from my point of view. This is why I
would like to add a Build System chapter.
Sure this makes sense however as a new user working through the Quick Start a
link to how configuration is handled is important, it provides a clear hint at a
possible next step and a new user does not have to had read the entire document.
I will add a reference to the "Build System" chapter.
