- The autoconf.h header file, generated with the current Kconfig configurations, is added as a build dependency. - autoconf.h depends on the proper tool (genconfig) and a Kconfig.dep which contains the dependencies for the given application and board, this is generated from $(USEMODULE). - The menuconfig target is added, to allow the configuration of modules using the Kconfig system.
