Does anyone have an idea of what the problem/prolems might be when you
get this error?

I have just compiled und linked the example on two machines and do not
see the problem. Do you have other arm-elf-toolchains installed? Please
check the versions of the used tools (arm-elf-gcc --version, make
--version, arm-elf-ld --version, sh --version).
