Triaging old bug tickets... can you still reproduce this issue with the
latest version of QEMU? There should now be support for "normal" 68k
CPUs, too...

Ken,
this is known to currently *not* work. As Andreas has already indirectly
explained, qemu does not provide full m68k emulation.
Instead, it supports the reduced m68k instruction set of Motorola's ColdFire
CPU only.
If you need a QEMU version with full m68k support, please have a look at
Alright, I have created a page on the Debian Wiki which explains how to
properly set up a chroot environment for sbuild/m68k on Debian [1].
With this set up, I was able to increase compile performance
dramatically as compared to native m68k hardware or the Aranym Atari
m68k emulator.
Enjoy!
Debian currently runs on the 68020, 68030, 68040 and 68060 processors

Ken, is that really a bug in QEMU or is Debian expecting some Motorola
68k CPU rather than the ColdFire MCU QEMU emulates?
