[ Impact ]
In order to help developers with profiling, Ubuntu enabled frame-pointers for packages in the main archive.

The `Affects` packages were missed due to the packaging issues. These have been fixed on Oracular and can now be ported to Noble.

[ Test Plan ]

Look at the DW_AT_producer in the associated debug ELF file for flags. -fno-omit-frame-pointer should be present after the fix.

<package specific test plan goes here>

[ Where problems could occur ]

No source changes are made. The packaging fixes have enabled other security hardening flags. This could have unintended effects.

[ Other Info ]

changes in dpkg have been made to make sure frame-pointers are not enabled on s390x and ppc64el.
