Confirmed with readelf: el6, el7 and el8 all carry\n  RPATH=/opt/alt/pcre/usr/lib64 implicitly from libtool and are left alone.\n- This is a live defect, not a regression: the already-released\n  alt-pcre-8.42-1.el10 has no RPATH either. The %if rhel >= 10 QA_RPATHS\n  override above only relaxes the rpath checker; it never produced an rpath.",
