I mentioned this when we were chatting on IRC, but to repeat for
the general audience..

I think it'd be useful for support purposes if the configure
script summary printed details of how we setup the venv.
eg perhaps a summary for each python module of whether we
added it to the venv, or relied on te site packages:

   python venv: meson (site), sphinx (venv), avocado (venv)


With regards,
Daniel
