Yea, reading the makefiles.rst again, it does seem that -objs only is
intended for host programs. The fact that it works now is an accident.
Further use of -y is necessary as we also use module-$(CONFIG_SYMBOL) to
resolve cases where we only include the files if the configuration is set.
Makes sense to clean this up.
