This is because ./arch/sandbox/board/barebox.lds.S is missing these
variables. I don't know how much sense it makes to add these. You could
just try and add them as done in the other linker scripts.

This is a bug in the sense that you should be able to compile with DEBUG
defined, but otherwise you can just comment the lines out and ignore
this. It will have no bad effect on the resulting binary.
