It looks like your 'as' does not support m68k cpu targets, i would suggest
that
you rebuild it from the sources. Makeing sure you dont exclude any cpu
targets.

When you have done this you should get the following options.

-m68000 | -m68008 | -m68010 | -m68020 | -m68030 | -m68040 | -m68060
| -m68302 | -m68331 | -m68332 | -m68333 | -m68340 | -mcpu32 | -m5200

by default 'as' will asume an m68020 cpu without a fpu.
