Erm, I think you'd get better results with a "print" thrown in there;
the interactive REPL interpreter shows you the value, but if you run
this through python3 -c, it will not actually output it to the standard
output unless you tell it to. Maybe try:
... -c 'import sysconfig; print(sysconfig.get_config_var("SOABI"))'

This much I'd expect, try with the print() in there.

I... honestly don't understand how this can happen. I don't understand
why python3 -c 'sysconfig.get_config_var()' would output anything...
