kbuild: include config.mk when auto.conf is not older than .config
Since the Kconfig conversion, config.mk has been included only when
include/config/auto.conf is newer than the .config file.
It causes build error if both files have the same time-stamps.
It is actually possible because EXT* file systems have a 1s time-stamp
resolution.
The config.mk should be included when include/config/auto.conf is
*not older* than the .config file.
