The $(VERSION) should be depended on config.h change. For example, when RELEASE parameter is changed in make commmand, CONFIG_RELEASE need to be updated in defconfig file, and then message in version.h should be updated. The patch also fix a bug that a code path in make defconfig never be triggered because shell will treat [ ! -f $(KCONFIG_FILE) ] as false when $(KCONFIG_FILE) is not specified. (i.e. "$(KCONFIG_FILE)" == "") Tracked-On: #2412 Signed-off-by: Victor Sun <victor.sun@intel.com>
