Distros with glibc < 2.34 include:
Debian 11
CentOS 8 stream
Fedora 34
openSUSE 15.5
Slackware 15
These are not obsolete, so far.

Thanks for the patch. I was hoping that we didn't need to worry about
older platforms needing -ldl. Oh well.
The patch causes 'configure' to search for dlopen even when there's no
crypto library. 'configure' could instead use AC_SEARCH_LIBS only if the
AC_LINK_IFELSE fails (or simply put

It's still bad as it adds a hidden dependency that is invisible to rpm.
Right. In practice though since coreutils also links libcrypto

That only works if libopenssl-devel is installed.
Good spot.
I'd already pushed a fix for this at:

That only works if

Just a correction : xxh128 does try to be random. And quite hardly: a
significant amount of development is spent on ensuring this property.
It’s even tested with
