Currently, the SOABI suffix is only available by running the Python interpreter to ask `sysconfig` about the setting. This complicates cross compilation because the target platform's Python may not be runnable on the build platform. Exposing this in the header would allow for build processes to know what suffix to add to modules without having to run the interpreter.

The entire extension suffix is currently available from the pythonX.Y-config command which does not depend on a running interpreter (on Linux systems at least), for example:

$ python3.8-config --extension-suffix
.cpython-38-i386-linux-gnu.so

Is that not sufficient for your needs?

Ah, that does look like it is suitable (since it is a shell script). I assume it is a batch script on Windows (though I feel cross-compilation is far rarer there). Thanks.
