The common $DO variable is used by the multilib logic to control which target to multiplex. But the m68k subdir is also using $DO to control which target (m68k or fido) to build. As we flatten things to automake, this conflict shows up and breaks the m68k build. Just rename the m68k variable to something unique to avoid it.
