+Subject: [PATCH] Python modules check: Assert exit code, not empty output
+
+Distutils is deprecated in Python 3.10+:
+https://www.python.org/dev/peps/pep-0632/
+
+When importing it, there is a warning:
+
+    DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives
+
+The configure script falsely assumed this is an error.
+Instead, we now check for the exit code, which is more explicit.
+
+In the long term, we need to migrate away from distutils, this is a stopgap measure only.
