A bit of context : 

I am trying to keep my buildroot project in git, but I am trying to 
cleanly separate "changes made to git" and "changes due to my project.

that basically means that all config file needs to be out of the 
buildroot/ subdirectory to be able to easily generate patches against
mainline and still keep my changes in git. I do that using git-subtree

I also change the location of the kernel config file for the same reason
and would do that for ctng and busybox if I needed to change them from
their default config
