You don't say what version of binutils you are using. I suspect that it
is sufficiently old that it doesn't have support for assembling for the
920. Possible solutions to this are:
- Upgrade binutils
- Target a different processor (try StrongARM for example).
- Use -march=armv4t -tune=arm920t (This will give you the same code as
with -mcpu=arm920t, but will pass armv4t to the assembler instead (it's
far more likely to accept that))
