If you want buildroot to build the kernel for you,
you need to ensure that LINUX26_KCONFIG
is defined as a link to your ".config" file when
the linus kernel is built.

The difference is that it will be one less script to run
you will get the modules automatically inserted into the root file system,
and the result will be in the binaries directory.

With the Advanced Kernel Configuration, you should be able to build 
basically
any kernel version, and you are able to apply patches much more freely
than before.

If you use the same version as the kernel headers, then
your kernel version choice is rather limited, and
if you choose to go with the latest, then the kernel version
will be updated once or twice a month.
