Now that kconfig can load multiple configurations, it becomes simple to integrate the split config step, by simply comparing the new .config file with the old auto.conf (and then saving the new auto.conf). A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).
