Your package fails to build with the newest autoconf-2.71, which was part of a recent wide Fedora change. More information about Fedora autoconf Change available here: https://fedoraproject.org/wiki/Changes/Autoconf_271#How_To_Test. The easiest way to reproduce the problem is to execute a fedora scratch-build on your package. Thank you for cooperation!
The logs at https://kojipkgs.fedoraproject.org//packages/libreoffice/7.2.0.4/3.fc36/data/logs/x86_64/root.log seem truncated so maybe there was a timeout rather than a problem with autoconf. I'll try a scratch build to verify.
