Sorry. I did forget about the required patch in Qemu:
See here:
http://lists.busybox.net/pipermail/buildroot/2012-April/052585.html
Or just the patch:
http://www.openadk.org/coldfire/qemu-2.1.0-m68k.patch

Hope this helps, otherwise I can prepare a Qemu (static build) if
required.

best regards
 Waldemar
