This has been completed and we reproduced ~1700 extra packages when building with a GCC-6 with this patch, as well as a patched dpkg that sets the environment variable appropriately.
This is about 6.5% of ~26100 Debian source packages, and about 1/2 of the ones whose irreproducibility is due to build-path issues. Most of the rest are not related to GCC, such as things built by R, OCaml, Erlang, LLVM, PDF IDs, etc, etc.

The dip afterwards is due to reverting back to an unpatched GCC-6, but I'll be rebasing the patch continually over the next few weeks so the graph should stay up.
