> It fails to build in Debian too.

@xnox hey Dimitri, the build breakage in Debian is not the same as the one in Ubuntu:
https://buildd.debian.org/status/package.php?p=mono&suite=unstable

In Debian, it builds fine with s390x, but doesn't for kfreebsd (and this latter arch is not supported by Ubuntu anyway, AFAIK).

So can we revisit dropping s390x arch for Ubuntu? Otherwise, if these latest fixes are not included in Ubuntu 20.04, nuget (the default package manager for .NET) will not work in the next LTS because of some runtime crash that these latest patches fix.
