[New(ish)] Python 3.11.0

Here's the initial port for Python 3.11.0

I've tested on amd64 and sparc64.

Python upstream switched a number of autoconf things from command line
switches to environment variables. We may see it show up in later releases
of the other 3.x versions, but for now we'll just set what we need in the
3.11 Makefile.

This still suffers from the same problem 3.10 does where the readline module
does not build properly. (3.9 makes the same complaint, but somehow a
working version of the module gets built).

ok?
