Do you need to do anything special to get waf to use all of the build
machine's resources?  Waf was only capable of keeping about ~30% of a
16-core/32-thread workstation's resources busy during the rtems-libbsd
build at any time, even during the embarrassingly parallel stages of
the build.

If you have a stack of python dependencies to manage, consider using
pipenv instead of pip.  Pipenv combines pip with virtualenv in such a
way that different Python dependency sets don't conflict with each
other on the user's system.  In particular, the python virtualenv that
I need to build and test RTEMS will be completely independent of the
virtualenv that I need for my own project's dependencies.
