No, the way buildroot works is that you decompress a linux kernel and patch 
it.
Then you can copy  $(LINUX26_KCONFIG) (defined by buildroot make 
menucconfig)
to the $(LINUX26_DIR)/.config.

$(LINUX26_KCONFIG) is of course generated by doing make xconfig inside the 
linux kernel
and then copying it to the buildroot directory.

This method meet my need to easily be able to select a working configuration 
for Linux.

I am doing the same for u-boot. A file is copied to 
include/configs/<board>.h
but there are somethings which always needs to change for a new user,
and these things need to be configured using buildroot "make menuconfig"

One of my main requirements is a consistent interface and ideally
everything is using the same configuration system.
The problem with using Kconfig is that it generates a single .config file.
It would be nice if it could generate one .config per package.
buildroot, linux, u-boot, busybox.

You don't allow u-boot to have hooks for out of tree patches.
To be successful, there needs to exists a number of place holders
where the developer have total control and simply can copy in out of tree 
stuff.
Relying on patching existing files makes upgrading your out of tree 
structure
unneccessary time consuming.
