[Arm-dev] configs directory, compiling a custom kernel for ARM

[Chris Szilagyi]

I finally ended up working around the problem by adding a copy statement 
in the kernel.spec file, just after it runs the scripts to generate the 
configs, to manually copy my working config file to the 
BUILD/kernel-*/linux-*/ folder.  From there it looks like the scripts 
pick it up and then place it in to the BUILD/kernel-*/linux-*/configs/ 
folder.  But initially I still am not sure where it tries to get them 
from initially.
