Some distribution discussions on this patch:

  /usr/bin/ld.so as a symbolic link for the dynamic loader

  <https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/SA244MNX5CC5OED65SX3QNCLKDUKW7D3/>

  <https://lists.debian.org/debian-devel/2021/12/msg00032.html>
  (thread wasn't Cc:ed to both lists throughout)
