It looks src/distrib/distrib/evbarm/instkernel/instkernel/Makefile
builds .img as "binary" and it doesn't care about .ub format.

Maybe we need the same ${TOOL_MKUBOOTIAMGE} magics in
src/distrib/distrib/evbarm/instkernel/instkernel/Makefile
as mk.marvell does?

We should have a simple script to invoke ${OBJCOPY} and
${TOOL_MKUBOOTIMAGE} ant share it between mk.marvell and
instkernel/Makefile?
