* Wed Feb 01 2023 Peter Jones <pjones@redhat.com> - 3.0.11-8
* Tue Feb 21 2023 Peter Jones <pjones@redhat.com> - 3.0.11-12
- Build with --no-warn-rwx-segment, since we don't wind up with segment maps
in the final bianries anyway.
- Add .note.GNU-stack sections to all the .S files we build.
- Don't use _hardened_ldflags since it's meant for GCC rather than ld and
doesn't do anything meaningful for us anyway.
