+Subject: [PATCH] Fix not having a default python interpreter version on
+ targets.
+
+This change adds a toolset requirement that sets the python version
+feature of the first configured python for a given target OS (usually
+the host OS). This allows to correctly configure different python
+interpreters for different target OSes.
