- On el10 only, export LDFLAGS with -Wl,-rpath=%{_libdir} before configure. The el10 toolchain emits neither RPATH nor RUNPATH, so /opt/alt/pcre/usr/bin/pcregrep failed to start with "libpcre.so.1 => not found" even though the package ships that library, and the QA integrity check flagged it. Confirmed with readelf: el6, el7 and el8 all carry RPATH=/opt/alt/pcre/usr/lib64 implicitly from libtool and are left alone. - This is a live defect, not a regression: the already-released alt-pcre-8.42-1.el10 has no RPATH either. The %if rhel >= 10 QA_RPATHS override above only relaxes the rpath checker; it never produced an rpath.
