Fix warnings where undefined vars are used. Make Kconfig emit "FOO=" for unset bool options To ensure make variables are always defined, even if empty. When writing auto.conf, include symbols disabled by dependency to make sure all make variables are always defined. Fixes espressif/esp-idf#137 Cherry-picked from https://github.com/espressif/esp-idf/pull/138
