The shipping default setting for the Freescale M5208EVB board is to run
the CPU at 166.67MHz. The current qemu emulation code for this board is
defaulting to 66MHz. This results in time appearing to run way to slowly.
So a "sleep 5" in a standard ColdFire Linux build takes almost 15
seconds in real time to actually complete.
Change the hard coded default to match the default hardware setting.

This solution is as good as another, so:

Thanks for the review.
By the way, we still do not have a m68k maintainer yet ... Laurent,
maybe you could finally send a pull request for that patch here:
Meanwhile, Peter, could you please take this patch here from Greg
directly? Or should it go via qemu-trivial instead?
