No more automagic bytecompilation

[Petr Viktorin]

Did you know that if you put a .py file outside /usr/lib/pythonX.Y/, 
rpmbuild will automatically byte-compile .pyc/.pyo for it?
Using Python 2 by default?

I find this (and especially the details of how it's done) too 
surprising, too limited and too hard to configure properly.
Miro and I are drafting a Fedora change to eventually switch to doing 
the byte-compilation explicitly instead. Files in /usr/lib/pythonX.Y/ 
still get compiled automatically, of course.
