As discussed recently, removing any manually configured python targets and
letting portage work its magic, rather than fighting against it, is usually a
sound way to get out of such a muddle.
I sync'ed portage a few hours ago today. Neither mako, nor setuptools require
anything other than python3_8 on this system:

I expect in a few weeks the tree will settle on python3_9, so all this rinse
and repeat exercise with all the python updates should hopefully go quiet. :-)
