Use IDF_PATH instead of SDK_PATH for the environment variable pointing to esp-idf This will require a matching change in all projects using ESP-IDF. 2016-08-19 02:32:35 -04:00			`KCONFIG_TOOL_DIR=$(IDF_PATH)/tools/kconfig`

make: add defconfig, don't run silentoldconfig before menuconfig This commit fixes the case when new Kconfig configuration options were added and you run `make menuconfig`.
