+Subject: [PATCH] selftests/functional/test_basic.py: prevent unversioned
+ Python
+
+`examples/tests/simplewarning.sh` calls a generic avocado command,
+which gets added to the path by the test code. That generic avocado
+command is `scripts/avocado`, from the source repository, which
+contains the unversioned `/usr/bin/env python`.
+
+Under some environments, such as Fedora >= 29, there may be no
+unversioned Python binary.  Let's respect the UNITTEST_AVOCADO_CMD
+environment variable, and add the the directory containting that
+binary to the PATH.
