This is not a bug.  This is deliberate.  Although in general the
linker is able to convert object formats on the fly, it is not able to
do so for all formats, and arm-coff is one of them.

There is a simple solution however.  Just link the application as
normal and then use objcopy to convert the executabel into the binary
format.  ie:

        arm-coff-ld -e _hello -o hello.cof hello.o init.o
        arm-coff-objcopy -O binary hello.cof hello.bin

Cheers
