Kazu, thank you for pinning down the change related to the
failure.  Perhaps it might help Honza to know that this failure
also happens for mn10300-elf and cris-axis-linux-gnu (supposedly
the other cris targets too), and worked on the 21:st and 22:nd,
respectively.  Therefore I presume those failures are caused by
the same patch.  I don't see this failure on non-CC0 simulator
targets (those that work :-/) so I guess this is related to
some CC0-handling code.

Honza, it would be very nice if could take the few steps and the
CPU cycles to test "wide" generic changes on
mn10300-elf+mn10300-sim as per simtest-howto.html.

For mn10300-elf, the failure is as follows:
