I developed a fix that can byte compile only the .py files in
site-packages. It involved creating my own version of
brp-python-bytecompile, preventing brp-python-bytecompile from running,
and running my-python-bytecompile instead.
The relevant statements in the spec file are as follows:
Before the description insert (from the Fedora packaging python page):
# Turn off the brp-python-bytecompile script
%global __os_install_post %(echo '%{__os_install_post}' | sed -e
's!/usr/lib[^[:space:]]*/brp-python-bytecompile[[:space:]].*$!!g')
At the end of the %install (following copying of the doc directories into
the buildroot) insert:
~/my-rpm-macros/my-python-bytecompile
The code for my-python-bytecompile is simply a copy of
brp-python-bytecompile with the final section commented out. That section
does files in directories other than site-packages. The code is below.

# .pyc/.pyo files embed a "magic" value, identifying the ABI version of
Python
# bytecode that they are for.
#
# The files below RPM_BUILD_ROOT could be targetting multiple versions of
# python (e.g. a single build that emits several subpackages e.g. a
# python26-foo subpackage, a python31-foo subpackage etc)
#
# Support this by assuming that below each /usr/lib/python$VERSION/, all
# .pyc/.pyo files are to be compiled for /usr/bin/python$VERSION.
#
# For example, below /usr/lib/python2.6/, we're targetting /usr/bin/python2.6
# and below /usr/lib/python3.1/, we're targetting /usr/bin/python3.1
