Set up some Makefile variable for different --features args
Set up some Makefile variable for different --features args

When specifying features min or systemd_compat always specify
--no-default-features, which would be dbus.

Don't do this with --features extra. extra is in addition to defaults,
as it must pick one or the other of the IPC mechanisms.
