See github #311 https://github.com/espressif/esp-idf/issues/311 Should fix weird compiler/linker bugs where config says something is enabled, but build system says it is disabled. Particularly noticeable when WiFi/BT libraries fail to compile/link despite being enabled. Underlying cause is configuration file regenerating, but component Makefiles not reevaluating. Entirely removes the idea that we don't need to generate config for some targets (like 'clean'). We need valid config for these targets, otherwise they don't know which files to clean (etc).
