--- Comment #4 from Andreas Schwab <sch...@linux-m68k.org> ---
Makefile.def already has the required dependencies:

dependencies = { module=all-target-libgo; on=all-target-libbacktrace; };
dependencies = { module=all-target-libgo; on=all-target-libffi; };
dependencies = { module=all-target-libgo; on=all-target-libatomic; };
