Now that the relevant osstest patches are in and stable, I revisited
this.  The downside risk to the release is very modest.  It might
cause some temporary test breakage but is very easily reverted.

The upside is that this will accelerate the total removal of qemu-trad
by about one release cycle.  That is highly desirable.

And pushed to staging.
