binutils-2.9.1 has both -m68360 and -mcpu32, which of course have the same
effect.  I believe egcs-1.1.1 now includes both of these options as well.  If
you end up using gcc-2.8.1, you may want a CPU32 version of libgcc.a and
newlib.  Here's my build procedure for them:

% cd binutils-2.9.1
% ./configure --prefix=/home/tools-gnu/`uname -s` \
? --target=m68k-unknown-coff -v
% gmake all info install install-info

% cd gcc-2.8.1
% gpatch -p1 < ../crossgcc-gcc-2.8.1.patch
% ./configure --prefix=/home/tools-gnu/`uname -s` \
? --target=m68k-unknown-coff --with-gnu-as --with-gnu-ld -v
% sed -e '/^MULTILIB_OPTIONS.*=/s/m68020/&\/m68332/' \
? -e '/^MULTILIB_MATCHES.*=.*m68000=m68332/s/m68000=m68332//' \
? -e '/^MULTILIB_EXCEPTIONS.*=/s/$/ *m68332\/*m68881 *m68332\/*msoft-float/' \
? Makefile > Makefile.cpu32 ; mv Makefile.cpu32 Makefile
% gmake LANGUAGES="c" all install

--OR--

% cd egcs-1.1.1 (in testing)
% ./configure --prefix=/home/tools-gnu/`uname -s` \
? --target=m68k-unknown-coff --with-gnu-as --with-gnu-ld --with-newlib -v
#*** Replace references to LANGUAGES="c c++" with LANGUAGES="c" in Makefile ***
% make cross install-cross
