unable to configure for m68k

[Bart Locanthi <bart@sabl.com>]

hi, i'm trying to build a cross-compiler on linux to target m68000, and 
i think the coldfire variant.

however, when i try to configure/make it, i get a message about the 
assembler not knowing about the 68020.

i've tried telling configure to only target the 68000 but that option 
doesn't work for m68k.

here's one of many things i've tried:

% ./configure --prefix=/usr/local/68k --target=m68k-none-elf 
--with-gnu-as --with-gnu-ld
% make
...

make[1]: *** [crtbegin.o] Error 1
make[1]: Leaving directory `/usr/local/src/gcc-3.4.0/gcc'
make: *** [all-gcc] Error 2

suggestions welcome.
