Are we able to raise this to GCC 13.1.0 now that it's released?

Certainly, although GCC 13 has been released, the upgrade for crosstool-ng is still in progress. We would like to catch up with the Rust 1.71 release, and since LoongArch CI is not dependent on GCC 13, I propose that we upgrade after crosstool-ng is ready, possibly through a new PR.

If crosstool-ng is ready earlier than expected, I would be happy to include it in this PR.

Ah yes. I forgot we privately talked about this a while ago.
