At Wind River we've discussed using the kernel configuration fragment patching 
process as a way to control busybox.  This would allow the recipe to provide a 
default fragment (configuration), with machines, architectures, and other 
configurations providing additional fragments -- that together would produce the 
busybox that the end use wants.

I think this is a better long term approach then hacking the defconfig file each 
time it's not quite right for a system.  (We may still need to modify it over 
time, but the modifications need to be considered "generic" based on the use of 
busybox in say core-image-minimal...)
