The build process generates bad ELF files which won't load.  The problem is
that the image and initrd segments have a load address of 0 and are not marked
as loadable.  The claim failed comes from OF trying to allocate memory at 0 for
those segments.  I experimented with trying to generate proper ELF files, but
was never fully successful on a G3 Mac.
