That bump will for sure introduce new breakages while fixing some we already
know about. But we had to make that bold movement at some point because that
make us use almost upstream GCC with very few off-the-tree patches for ARC.

And indeed our goal is to find and fix as many issues as we can in that new
toolchain. So we'll continue to monitor BR autobuilder failures on daily basis.

As usual it would be good to rebuild BR pre-built tools for ARC out of this
commit so we have better coverage in running build jobs.
