This patch is now applied, but it does not actually solve the problem:
gcc is the metapackage, with a >= dependency on the actual compiler
(currently gcc-8).
In other words, gcc-8 8.2.0-3 currently in testing can be used to
fulfill the dependency on gcc (<< 4:8.1.0.0).
Also note that gcc-8 in unstable is constantly following the upstream
stable branch, there is not actually bigger changes when upstream
happens to cut a release from this branch.
Realistically, gcc major version is the the only thing that is feasible
to do.
