Toolchain+Ports: Update GCC to 13.1.0

This is a mostly straight-forward rebase of our patches on top of
13.1.0. The spec files needed a change, as GCC no longer supports STABS
debug information, but we were building GCC with support for it.

Highlights of this release include static `operator()`, The Equality
Operator You Are Looking For and extended `constexpr` support.
