There's a closed pull request on the void-packages repository

gcc: update to 12.2.0.
https://github.com/void-linux/void-packages/pull/34902

Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->
[ci skip]

Edit: this PR had been updated for gcc 12.2.0

There are lists of failing builds here: https://github.com/void-linux/void-packages/issues/39809, https://github.com/void-linux/void-packages/issues/39960

I tested this PR with glibc and after updating glibc, it seems to work fine.
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 12 doesn't appear to result in any issues. (more testing is needed)

Please let me know if there are any issues.

I compiled base-system and base-chroot on x86_64-glibc and x86_64-musl to ensure that compiles and it appears to work fine.

I tested some of the cross compilers and after some debugging with the help of CameronNemo, we figured out the issue.
The cross compilers are built with `nopie=yes` (specified in environment/build-style), which causes issues with glibc 2.35+ which uses PIE by default.
gcc always builds itself as nopie.
I added a workaround to common/build-style/void-cross but if you have any other recommendations on how to handle it, feel free to let me know.

This PR also updates glibc to 2.36:
