Not Able to Build Some Versions of Python on M1 at 12.3.1

I tried to build these versions from the source and still get build failure. For example building 3.6.9 from source results in the following.

By default, distutils will build C++ extension modules with "g++". If this is not intended, then set CXX on the configure command line.

Hi @mikeyh, thanks for your solution! Indeed, there is no issue with 3.8.13. However, I need python 3.8.9 or under. I checked pyenv's github page, but I can't find patches for 3.8.*. Do you know how to solve the problem? Thanks a lot.
