I did originally write a patch which might have solved this problem - it force the build to use U-Boot headers except for a few special cases. You might be able to find it in patchwork (archived?) But I think Masahiro came up with what I thought was a better way - more general purpose than my patch. You have I think the opposite problem to what I was facing. I'm not sure of the best general approach now. I suggest you experiment and see if you can come up with a suitable patch.
