cross build toolchains for mc68000

Hello world :-)

I would like to identify a cross platform development build toolchain
for MC68000 targets such as 16-bit Atari and Amiga.

I cannot quickly find such toolchain with `pkg search mc68000` nor
`make quicksearch key=mc68000" in the ports tree.

I did find some tools for 8-bit MOS6502 at port tree:
make quicksearch key="6502"
Port:   acme-0.97.r319,1
Port:   cc65-2.19
Port:   dxa65-0.1.4
Port:   vasm-1.8c
Path:   /usr/ports/devel/vasm
Port:   xa65-2.3.11
Port:   p5-Acme-6502-0.77_2
Port:   nesasm-20040314_1

Do we have such dedicated toolchains for MC68000? Maybe generic
GCC/LLVM can generate binaries for those targert?

Any hints welcome :-)
