While that may be true, I suspect that this is just an instance of a
known bug in the toolchain. This is happening when objcopy is being
used to generate redboot.img an ELF file with the debug info stripped
out.  The message is not seen when linking to create redboot.elf or
generating redboot.srec and redboot.bin from it.

This bug is actually entirely benign, it is only a warning,
redboot.img gets generated correctly. Something in the BFD library is
just confused and the conditions for generating this message are
wrong. It should go away with newer versions of binutils.
