Now I've come back to this, & done (essentially):

powerpc-rtems-objcopy -I binary -O elf32-powerpc tarfile tarfile.o

& then linked in the tarfile.o, using ld as an intermediate step.  I'm now
getting a fat warning "cannot represent architecture UNKNOWN" at the
objcopy, and undefined _binary_tarfile_start and _binary_tarfile_size.

So:

- Is the warning significant?
- Where do the start & size values come from?

TIA
