Since "reload_completed" is referenced, this is only about the CC0
conversion, right? Switc

-m68020-40 and -m68020-60 since global_options_set is not touched by
the evaluation code for -m68020-40 and -m68020-60 in m68k_handle_option.
This patch was tested by checking the -dM output of a patched cc1 for
the present __mc680X0__ macros.

These compound options are supposed to cause m68k.c/m68k_option_override

Right. Maybe a better solution would have been

IMHO, the patch is incomplete.

FWIW, the prototype for m68k_final_prescan_insn in m68k-protos.h was
not removed.

this target is only about m68k it was no problem to use old(er) binutils
versions. Especially if a target cares only about m68k I would like to
see the legacy m68k options retained.
