There is a new pull request by Oreo639 against master on the void-packages repository

https://github.com/Oreo639/void-packages gcc11
https://github.com/void-linux/void-packages/pull/34902

gcc: update to 11.2.1git20211128
<!-- Uncomment relevant sections and delete options which are not applicable -->
[ci skip]

Note: depends on https://github.com/void-linux/void-packages/pull/32330
(Otherwise, it would work until you try recompiling glibc)

I tested this PR with glibc and it appears to work fine so far, aside from the issue mentioned earlier.
I also tested this PR with x86_64-musl, and it appears to run fine in a musl chroot, and recompiling and installing musl with gcc 11 doesn't appear to result in any issues.

Please let me know if there are any issues.
