Thanks for applying the patch, but I believe you have the cause and
effect reversed in your thinking about this system.

The entire point of dpkg-buildflags is to pass the -ffile-prefix-map
and -fdebug-prefix-map arguments to GCC. There is nothing to fix as
their entire purpose is to pass this varying path to GCC. The only
"fix" possible would be to remove this mechanism entirely, defeating
the goal of being able to do a reproducible builds in the first place.

In other words, if a package happens to trigger that Lintian tag, then
that is (correctly) informing the maintainer that it is (incorrectly)
recording this inconsequential build path in a binary artefact and
is something for the maintainer to address.

Hope that clarifies things on your end, despite this being somewhat out
of scope for this bug report.


Best wishes,
