add some basic infrastructure for qemu-system-m68k
Qemu emulates a Coldfire Evaluation board without MMU.
As that is the first non-MMU platform in OpenADK I added
ADK_TARGET_UCLINUX. Mksh can not be used for non-MMU, because
it requires fork() for job control and other things.
We use hush here. non-MMU support in uClibc does not have
shared library support.
Kernel does not start yet. So no runtime testing, but at least
coldfire toolchain can be tested with uClibc-ng.
