# pygobject with python3 support requires recent versions (e.g., 3.28.3 --
# http://crrev.com/c/1869550), but recent versions are more difficult to
# cross-compile (gobject-introspection, in particular). Leave this behind an
# optional 'dbus' USE flag for now. Hwsim tests will skip D-Bus tests if
# libraries aren't available.
