I ran a few times into an issue where a system would not create debuginfo packages. The page https://fedoraproject.org/wiki/Packaging:Debuginfo did not help me.
It turned out to be a missing redhat-rpm-config package.
Please a note about needing this package at https://fedoraproject.org/wiki/Packaging:Debuginfo
Looks like it was already mentioned on that page: "The discussion on this page assumes that the redhat-rpm-config package is installed." I've put that into a note box so it's harder to overlook and changed the wording slightly to make it more clear why redhat-rpm-config is necessary.
