[opensuse-buildservice] Factory/Tumbleweed i586 unresolvable - missing pre/vminstalls: kernel-obs-build

On Factory/Tumbleweed i586 many packages get the error "unresolvable - missing pre/vminstalls: kernel-obs-build" when trying to rebuild. See eg. https://build.opensuse.org/project/monitor/multimedia:apps https://build.opensuse.org/project/monitor/devel:languages:php Many home repositories are also affected, too.
