rpmbuild: how to handle byte-compilation between RHEL6's python-2.6 and RHEL7/Fedora's python-2.7

[ryran]

I mean, the rpm works on all versions now, but it includes byte-compiled files for python-2.7 which means every time someone runs it on RHEL6, it's generating those and then trying to write them.

The correct approach would be to have a separate rpm for RHEL6 vs RHEL7+ ... sigh.

The other ("incorrect") approach would be to exclude such files in the rpmbuild and have a postinstall script that generates them.
