That looks good to me.  After your test is pushed in, I'll push my
rl78 and rx patches in, and remove the kfail from this test.  My
rl78 and rx patches should go to 7.12 branch, but I am not sure
this test case should go to 7.12 or not.

Yes, PR 20939 is about host arch, but such test does find other issues,
like PR 20955.  Other issues are shown up after the rl78 and rx segment
fault is fixed.
