We have encountered recently an issue when building VTK, where we have discovered that that mingw-python gives a wrong value for SOABI
on Ubunut 22.04:

>>> import sysconfig; print(sysconfig.get_config_var('EXT_SUFFIX'))
.cpython-310-x86_64-linux-gnu.so
>>> import sysconfig; print(sysconfig.get_config_var('SOABI'))
cpython-310-x86_64-linux-gnu
>>> import sysconfig; print(sysconfig.get_config_var('SO'))
<stdin>:1: DeprecationWarning: SO is deprecated, use EXT_SUFFIX
.cpython-310-x86_64-linux-gnu.so

on mingw-python/CLANG64

>>> import sysconfig; print(sysconfig.get_config_var('EXT_SUFFIX'))
.cp310-mingw_x86_64_clang.pyd
>>> import sysconfig; print(sysconfig.get_config_var('SOABI'))
cpython-310
>>> import sysconfig; print(sysconfig.get_config_var('SO'))
<stdin>:1: DeprecationWarning: SO is deprecated, use EXT_SUFFIX
.cp310-mingw_x86_64_clang.pyd

SOABI should returns cp310-mingw_x86_64_clang

On MSVC Python, SOABI isn't there in sysconfig.get_config_var, so I would say we should remove that rather than return the wrong value. We try to match with MSVC Python as much as possible. Is there any specific use case where you would use that value?

CMake looks for SOABI if it is not found It looks for EXT_SUFFIX, so I have no use for it.

Changing my mind, changing could really break quite some things, there are a lot of other things not matching MSVC python there. Fixing SOABI seems simple, will have a look.
