Comment 3 for bug 2038583

Studying this more, this is likely to only affect trying to run libc6-s390 that is from 18.04 bionic or older. As later versions of libc6-s390 wrap 64bit syscall, instead of calling 32bit syscall directly.

However, ideally we would drop all s390 (31 bit) binaries from Ubuntu, and turn off COMPAT / COMPAT_32BIT_TIME in the kernel.
