+commit 7cf1ad2dbb5af9b9012ba67b9687ad28c02578d6
+Author: Panu Matilainen <pmatilai@redhat.com>
+Date:   Wed Feb 3 12:52:30 2010 +0200
+
+    Enable strict python bytecompile mode (if rpm supports it)
+    - with %_python_bytecompile_errors_terminate_build set to non-zero,
+      byte-compilation errors will abort the build, this helps catch out
+      silly "improt foo" syntax errors early on
+    - not all .py files are valid python (they can be templates, inteded for
+      jython consumption etc), and what's valid can depend on the python
+      version (notably 2.x vs 3.x) so allow overriding from spec
