I agree with Eric; while the workaround is to back rev the gcc and its
associated packages, I also build kernels straight from kernel.org,
usually within hours of their availability and this has been working for
me for many years, and it is not sufficient to justify this change by
saying doing so "isn't a good idea." A change of functionality of this
scope warrants a minor version number increase, this change was not
merely a bug fix.
As the kernel is the most important code gcc is ever likely to compile
on debian or any other distro for that matter, this change should be
backed out, and not reintroduced UNTIL the *official* kernel source is
ready for it.

The Debian kernel packages still have a dependency on gcc-5, which may mean
that the kernels are currently only built/supported with gcc-5.
vanilla kernels (Linus' tree and the stable ones) could be compiled just fine
with gcc 6.2.0-6 and that now fails.
I still think this is a major regression and regard gcc 6.2.0-7 simply as
broken.

Concurring with Wolfgang; pulling the source straight from kernel.org
and using identical .config files will work with 6.2.0-6 but fail with
6.2.0-7. I was able to build and install 4.8.3 with no issues after
back-revving gcc et. al. to 6.2.0-6

I think this is a major regression if you can't build vanilla and stable
kernels any more.
