Hi!
It appears that there's been a bug in rpm during the time of Fedora 26 mass
rebuild. The [bug] resulted in some packages failing to be rebuilt and some
being built without .pyc files inside __pycache__ directories.

[bug] https://bugzilla.redhat.com/show_bug.cgi?id=1411588

Together with ignatenkobrain and sgallagh who alerted us to the issue, we've
managed to narrow down affected packages to Python 3–only packages that don't
drag Python 2 into the buildroot and don't use standard Python build/install
macros.

In the end the following 22 packages were rebuilt:

antimony  (antimony-0.9.3-0.3.20161128git41a770.fc26.src.rpm)
btest  (btest-0.54-7.fc26.src.rpm)
