Comment 9 for bug 1520033

Sorry for dropping the ball on this.

We have 3 options:

1) Drop s390x for Focal

2) Backport a commit which, in testing, inexplicably appears to fix s390x, at least on Debian Sid - but there's a LOT of churn around it, so it's tough to backport (491a4d5da8e523d6191e6027ea7f3cee226d6ba8)

3) Update to at least Mono 6.8 (6.6 is definitely bad, 6.10 is definitely good, the relevant commit would _just_ have missed the 6.6 branch date so should be in 6.8)

Personally, I think option 3 is the best of the 3.
