python3.10 builds and works under Solaris10 update 11 as downloaded
today from Oracle. The compiler in use was gcc5 from OpenCSW. On the
way of getting functional bootstrap I had to butcher a few other
packages (e.g. libuuid lacking errx - just took them off for now).

Anyway:

➜  ~ uname -a
SunOS s10u11 5.10 Generic_147148-26 i86pc i386 i86pc
➜  ~ python3.10
Python 3.10.0 (default, Oct 13 2021, 20:13:42) [GCC 5.5.0] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> print(sys.version)
3.10.0 (default, Oct 13 2021, 20:13:42) [GCC 5.5.0]

_crypt module doesn't build. I had to 'bmake print-PLIST > PLIST &&
bmake repackage' because of this and two other modules with fake in
their names - built but not importable.

So there is some work to be done, but it is certainly better than
saying that only 3.6 is working under Solaris 10.
