Title:
  Removal of 31-bit (s390) glibc packages

Status in Ubuntu on IBM z Systems:
  Fix Released
Status in glibc package in Ubuntu:
  Fix Released

Bug description:
  Last cycle there was the effort to turn off COMPAT_32BIT_TIME on s390x (but also on other architectures, LP#2038583).
  Based on this effort it was agreed to not only turn off 32-bit time but 32-bit (for the mainframe platform, that is technically 31-bit) entirely.

  Two major 31-bit “left-overs” for the mainframe platform are the
  31-bit glibc packages (libc6-s390, libc6-dev-s390).

  This should be cleaned-up and these should now be removed (and their
  build disabled) to reach a clean 64-bit s390x system.

  But the reverse dependency situation is like follows:

  $ reverse-depends --list libc6-s390 -r oracular -a s390x
  gcc-snapshot
  lib32asan5
  lib32asan6
  lib32asan8
  lib32atomic1
  lib32gcc-s1
  lib32gfortran5
  lib32go14
  lib32go16
  lib32go19
  lib32go21
  lib32go22
  lib32go23
  lib32gomp1
  lib32gphobos1
  lib32gphobos2
  lib32gphobos3
  lib32gphobos4
  lib32gphobos5
  lib32gphobos76
  lib32itm1
  lib32objc4
  lib32stdc++6
  lib32stdc++6-10-dbg
  lib32stdc++6-11-dbg
  lib32stdc++6-12-dbg
  lib32stdc++6-13-dbg
  lib32stdc++6-14-dbg
  lib32stdc++6-9-dbg
  lib32ubsan1
  lib32z1
  libc6-dev-s390
  oaklisp

  $ reverse-depends libc6-s390 -r oracular -a s390x

  But since kernel dropped support for 31-bit (32-bit) executables,
  starting with Ubuntu kernel 6.8 (LP#2038583, esp. comment #7 and #11)
  these libraries should be removed, too.
