+  * d/rules: wrap _PYTHON_SYSCONFIGDATA_NAME setting to cross-compile case
+    On e.g. buster, _PYTHON_SYSCONFIGDATA_NAME is different, so this assignment
+    does not work right.  In order for it to work on buster, add condition on
+    host vs build gnu type. This breaks compilation with foreign python binary.
