Frédéric Bérat 7e2c1061c8 Enable hardening on libltdl loaders
While hardening flags were properly passed to make for the ltdl library,
the loaders (which are built separately), were not built with them.
Fix the dedicated patch for the loaders to be hardened.

libtool: Enable hardening in libltdl
See the rhbz#1289759 and rhbz#1214506. We disable hardening namely because
that bakes the CFLAGS/LDFLAGS into installed /bin/libtool and ltmain.sh files.
At the same time we want to have libltdl.so hardened. Downstream-only patch.
