The only generic code relying on this is linux-user, but linux users' default behaviour of defaulting ELF_MACHINE to ELF_ARCH will handle this. The machine model bootloaders can just pass EM_68K directly, as that is architecture specific code. This removes another architecture specific definition from the global namespace.
