Lintian info message "hardening-no-bindnow" with vanilla debian/rules

[Julian Gilbey <jdg@debian.org>]

Hi!

A package I maintain within the team (python3-pyxdameraulevenshtein)
gives the following lintian message:

I: python3-pyxdameraulevenshtein: hardening-no-bindnow [usr/lib/python3/dist-packages/pyxdameraulevenshtein.cpython-310-x86_64-linux-gnu.so]

The debian/rules file is very bland, essentially:

%:
        dh $@ --buildsystem=pybuild

and there is nothing about CFLAGS or the like in the setup.py file.
So if having this hardening flag enabled is a good thing, it should
probably be enabled somewhere within the pybuild system, rather than
every individual package with an extension file doing it.

Or have I missed something?

Best wishes,

   Julian
