For the folks on tech-toolchain:

The issue with objcopy is that it produces ECOFF files that older ROMs
won't boot.  These files have the wrong magic number.  While the magic
number can sometimes be changed and the file will boot, other times it
can't.  At least that's been my experience with elf2ecoff and my
Deskstation rPC44.
