All reports of binary-has-unneeded-section for the archive. The extended description of this tag is:
The binary or shared library is stripped, but still contains a section that is not useful. You should call strip with --remove-section=.comment --remove-section=.note to remove the .note and .comment sections.
dh_strip will do this automatically for you, but install -s will not because it calls strip without any arguments.
This tag has not been emitted in any package tested by Lintian.
