Last missing piece is being able to do "select FOO = n", which Stephen

I thought Linus' idea was to use:

KBUILD_KCONFIG=file make allnoconfig

in which case any option which would be presented to the user which hasn't
been selected by 'file' ends up being set to n.  That means there's no
need for a special "select FOO=n" construct.
