Title:
  buildd file owner/group for shared libraries

Status in debhelper package in Ubuntu:
  Fix Released
Status in fakeroot package in Ubuntu:
  Fix Released
Status in debhelper package in Debian:
  Fix Released

Bug description:
  fakeroot with glibc broke dpkg-deb for packages that do not use
  "Rules-Requires-Root: no" was broken.

  binutils stopped preserving permissions from objcopy & strip, leading
  to incorrect permissions of files after stripping.

  fakeroot is now patched with better glibc 2.33 support. TODO upstream
  changes.

  binutils is not fixed, as upstream changes are still being discussed.
  Instead we have worked around objcopy/strip in debhelper to call those
  tools from dh_strip in a safe manner.

  We also rebuilt binutils against glibc 2.32, to avoid this new
  behaviour. However, we need to resolve bintuils in a better way, one
  way or another.

  the current state of -proposed creates deb packages with buildd file
  owner/group for shared libraries.

  reported at least for kwayland-integration.

   - in a release pocket, rebuild binutils from proposed. correctly
     restores the file ownership

   - in a release pocket, update glibc from proposed. then rebuild
     binutils from proposed. shows the wrong ownership
