Yes, there is something a bit wrong with your kernel configuration. You get this error if 
there is no board selected to be compiled-in. Please go to kernel configuration and select
"System Type -> SAMSUNG EXYNOS SoCs Suppport". Then select some hardware board to be 
compiled in, for example SMDKV310, SMDKC210 and "Mobile NURI board".

Best regards
