This seems to work as expected and has the additional benefit of
skipping those "merge" commits by bors since those don't actually
change any files.

Under https://builder.wildebeest.org/buildbot/#/changes you can see
the "builds" for each change (some will now be empty if they didn't
touch any gccrs files).

Cheers,

Mark
