Title:
  [SRU] Enable frame-pointer on Noble in update-notifier

Status in update-notifier package in Ubuntu:
  Invalid
Status in update-notifier source package in Noble:
  In Progress

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

  https://ubuntu.com/blog/ubuntu-performance-engineering-with-frame-
  pointers-by-default

  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.

  The following scripts can be used as a reference

  The autopkgtests cover the Python parts, so we should start update-
  notifier on a real system and see that it still starts. We don't
  expect any regressions from compiler flag changes, so I don't want to
  do a whole bunch of UI tests or anything.

  [ 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.
