libutempter-pierelro.patch in libutempter-1.1.6-13.fc28 hard-codes linker flags, instead of using those from redhat-rpm-config. -specs=/usr/lib/rpm/redhat/redhat-hardened-ld is currently missing, so the resulting binary uses lazy binding. See https://src.fedoraproject.org/rpms/redhat-rpm-config/blob/master/f/buildflags.md for information on RPM macros and environment variables provided by the build environment.
