support/kconfig: add support for olddefconfig
olddefconfig is a new target available in kconfig that allows to take
an old .config file, and update it to the latest version of the code,
without being asked for questions: it automatically assumes the
default value for options whose value was not defined.
It for example allows to take a minimal defconfig, copy it as .config,
and do 'make olddefconfig' to get the full .config.
