[PATCH] allow /proc/config.gz to be built as a module

The driver for /proc/config.gz consumes rather a lot of memory and it is in
fact possible to build it as a module.

In some ways this is a bit risky, because the .config which is used for
compiling kernel/configs.c isn't necessarily the same as the .config which was
used to build vmlinux.

But OTOH the potential memory savings are decent, and it'd be fairly dumb to
build your configs.o with a different .config.
