The immediate specific need for the GCC update in oldstable and stable
is the Linux kernel, there are no plans to rebuild other packages in
released distributions at this point.
We might add this to the dpkg-buildflags default flags for buster
as a generic hardening measure, but that requires additional
work/consideration/discussion. Fortunately the buster freeze is
still quite some time away, so we're in the comfortable position
to evaluate without time pressure.
