Some kernel config symbols we need to enable in some configurations don't have a "prompt" entry in the Kconfig files, meaning that make oldconfig (or any other make fooconfig) won't change them. So we add a Kconfig.local where they can be selected In this patch we hardcode the required symbol. Next step would be to generalise so that they could be specified in something like a config.kernel.hiddenConfig attrset
