Title:
  preinst check for kernel release > 255 no longer needed

Status in glibc package in Ubuntu:
  Confirmed
Status in glibc package in Debian:
  Unknown

Bug description:
  When running in docker in (for example) AWS CodeBuild, the output from
  `uname -r` can include kernel version that the
  debhelper.in/libc.preinst (lines 140-152) dislikes when you upgrade
  `libc6`.

  Debian claim to have removed the offending section in glibc/2.31-14.
  See: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=987266

  Please can we have this fix ported into 20.04 Focal?

  Full Error:
  -----------------------------------------------------------------------
  ERROR: Your kernel version indicates a revision number
  of 255 or greater.  Glibc has a number of built in
  assumptions that this revision number is less than 255.
  If you\'ve built your own kernel, please make sure that any
  custom version numbers are appended to the upstream
  kernel number with a dash or some other delimiter.
