With the slr, bc 5,x is the correct mask, or course. So it must be something
else.
As I understand it s390 and s390x are exactly the same except the default -m31.
But I might be mistaken there as well. I certainly tried both in my struggle
with building the cross compiler. Have you perchance a crib sheet of how yours
was built?
