menuconfig of the kernel is a configuration tool and is not in
any way a frontend for make.

You use menuconfig to say what you want included in
your kernel.
This results in a file containing a lot of assignmnets
like this:

CONFIG_FOO = y
CONFIG_BAR = m


These assignmnets in combinations with some intellegent use
of the features og gmake allow us in the kernel to
use simle assignmnets to define what we want to build.

A typical kbuild fragment looks like this:

obj-$(CONFIG_FOO) += foo.o

So if CONFIG_FOO expands to 'y' then we append
obj-y the value foo.o and we use this to build
what is requested.

When you build the kernel you do two simple steps:

"make menuconfig" to configure your kernel
"make" to build your kernel.
