linux: add missing tls bindings

[mbyx]

Description

Adds missing TLS bindings for linux as mentioned in #3149. Tests should pass as long as the kernel used for testing implements them.

Sources

Previously only a part of the header had been implemented, now everything has been bound except for placeholder values (__TLS_INFO_MAX, TLS_INFO_MAX).

Checklist

• Relevant tests in libc-test/semver have been updated
• No placeholder or unstable values like *LAST or *MAX are
  included (see #3131)
• Tested locally (cd libc-test && cargo test --target mytarget);
  especially relevant for platforms that may not be checked in CI
  I was unable to test locally due to errors similar to Unable to run tests in libc-test using musl (Alpine Linux 3.18.2) #3305.

Permalink to the headers in their current state https://github.com/torvalds/linux/blob/99fa936e8e4f117d62f229003c9799686f74cebc/include/uapi/linux/tls.h (you can get these from the triple dot menu at the top right of the file view).

The CI failure just needs you to sort libc-test/semver/linux.txt, FreeBSD is spurious.

The test that failed gives the same errors that I experienced when testing my commit locally. Is it the CI system or something wrong with my implementation? It also cancelled the rest, so I can't check if the problem will occur for them all.

[tgross35]

LGTM and the CI problem should be fixed with #4311. Could you rebase and squash?

[tgross35]

Hm, are these headers just not available on loongarch musl for some reason? Cc @heiher in case you know something.

Thanks for your CC. I have pushed a PR (#4320) for that, and I believe it has fixed this issue.

[tgross35]

This should work now, @mbyx could you squash please?

[mbyx]

Sorry, but this is my first time having to squash, I think I'm not doing it properly, could you please guide me?

[tgross35]

The squash looks good, thanks!
