I have read old bugreport

xalan-c package needs source update for epel ppc64le/aarch64  https://bugzilla.redhat.com/show_bug.cgi?id=1198717

and I found out that at that time ppc64/epel7 was failing due

RHEL rpm config.guess does not support ppc64le
https://bugzilla.redhat.com/show_bug.cgi?id=1291377

that later, in 2016 has been fixed, so a simple rebuild will fix the problem.
I tried it on a Copr repo
https://copr.fedorainfracloud.org/coprs/germano/xalan-c-ppc64/build/723357/

Any progress?
Still there is no ppc64 package

FAS tibbs, that is proven packager, can help us in release bump, but we have to proof that the package works correctly (despite it compiles).
Tomasz do you have any idea how we could provide such proof?

Building xml-security-c package will be one of infinitely many possible proves.

xalan-c-1.11.0-4.el7 has been submitted as an update to Fedora EPEL 7. https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2018-20b37842f2

A buildroot override is also active, so you can build against the updated package in koji now.

Just have been able to build successfully xml-security-c for epel7.
