This adds a check to decide if Kconfig should run on a build. It will run if any of the following conditions is true: - A file with '.config' extension is present in the application folder - A 'Kconfig' file is present in the application folder - A previous configuration file is present (e.g. from a previous call to menuconfig) - menuconfig is being called This assumes that Kconfig will not generate any default configurations just from the Kconfig files outside the application folder (i.e. module configuration via Kconfig is disabled by default). Should this change, the check would not longer be valid, and Kconfig would have to run on every build.
