[Bug 1917390] [NEW] Executable test [ -x file ] fails after upgrading libc

[Owen Healy]

Public bug reported:

Steps to reproduce (on an amd64 machine):

    name=$(docker create --tty ubuntu:21.04 sleep inf)
    docker start $name
    docker exec $name apt-get update -y
    docker exec $name apt-get install libc6 -y
    docker exec $name bash -c 'if [ ! -x /bin/cat ] ; then echo no ; fi'

This will print 'no' at the end, indicating /bin/cat fails to test as
executable.

Release: hirsute
Architecture: amd64
Package: libc6
Version: 2.33-0ubuntu2

** Affects: glibc (Ubuntu)
     Importance: Undecided
         Status: New
