Package: debhelper,lintian
Severity: important
Some packages build with link time optimizations enabled, which is ok, whoever then these packages may ship with static libs which still have the LTO information in some sections of the object files (e.g. ext2fsprogs). This is not desired in most cases, so this information should be removed from these files, and not shipped in the archive. Plus the streaming format for the LTO information changes (even in GCC minor releases), and leads to build errors when you try to use an old streaming format with a newer compiler. I'm asking for 

 - dh_strip removing sections, as in

     strip -R .gnu.lto_* -R .gnu.debuglto_* -N __gnu_lto_slim -N __gnu_lto_v1

   which is turned on by default.

 - dh_strip providing an option not to remove these sections.

 - lintian warning about object files and static archives having such
   sections.
I'd like to see that implemented in debhelper, because LTO builds are also sometimes enabled in upstream sources.
LTO is turned on by default in Suse, and their dh_strip equivalent provides the functionality above for the removal of the LTO information.
Please feel free to split this issue into separate debhelper and lintian tasks once a solution is agree upon.

 .
   [ Niels Thykier ]
   * dh_installsystemd.1: Improve documentation about tmpfiles that
     are now handled by dh_installtmpfiles in compat 13.
   * dh_installtmpfiles: Prefer debian/package.tmpfiles over
     debian/package.tmpfile, but accept the old path with a warning.
     Thanks to Michael Biebl for suggesting the change.
   * dh_strip: Automatically strip Link-Time Optimization (LTO)
     symbols from static archives.  The format is not stable between
     compiler versions.  Thanks to Matthias Klose for the
     suggestion and for providing the exact options.
     (Closes: #939656)
   * dh: Tweak the command-skipping optimization to skip commands
     in a few more cases when the command is known not to react to
     command line options.
   * dh,dh_installsytemd*: Work around broken NOOP promise caused by
     dh_installsystemd* using nonstandard "package@" prefix for
     pkgfiles.  Thanks to Badreddin Aboubakr and Andy Caldwell for
     reporting it.  (Closes: #950723, #951819)
 .
   [ Nicholas Guriev ]
   * cmake: Verbose autogen rules.
   * cmake: Skip install all dependency with compatibility level 13 and
     above.

   [ Andy Caldwell ]
   * dh_installsystemduser: Fix bug that prevented dh_installsystemduser
     from installing parameterized services.  (Closes: #951819)

   * Update German translation (Chris Leick)  (Closes: #951917)
