If we were integrating kconfig, we should consider kconfig-frontends (http://ymorin.is-a-geek.org/projects/kconfig-frontends). But I'm not sure it is the way to go. You are welcome to open the debate in a dedicated thread by explaining the benefits compared to a configuration script. I think most of the options could be automatically guessed given the target CPU, kernel, libc and compiler. It looks like a scripting task, not a manual configuration (as kconfig provides). But maybe we can mix kconfig and some automatic defaults.
