[Fedora-packaging] rpmbuild changes in Fedora 23 Rawhide?

[Michael Schwendt]

Been running into a Rawhide rebuild failure caused by a strangely
packaged libcanberra-devel: https://bugzilla.redhat.com/1195363

First observation: The -devel package does not explicitly depend
on all three library base packages. => Two of the three .so symlinks
on the -devel pkg point to non-existing targets.

Closer look: There used to be _automatic_ Requires on the library
SONAMEs. Those are missing in the recently rebuilt libcanberra-devel
package.

Is this an expected change in rpmbuild for Rawhide?
