From your previous post, I understand that you are building for MIPS.
However, the kernel doesn't provide a "make uImage" target for the MIPS
architecture: you have to produce the mkimage'd kernel manually.

On the Buildroot side, we should just prevent you from selecting
"uImage" if the architecture does not support it.

Cheers,

Thomas
