Documentation for x86_64-unknown-linux-gnu is missing from `docs.rs`

The current documentation on docs.rs is missing the x86_64-unknown-linux-gnu platform: https://docs.rs/socket2/0.5.8/socket2/

The documentation build logs can be seen at https://docs.rs/crate/socket2/0.5.8/builds

Key takeaways:

A new documentation build was run on 2025-02-22. An older build for the same version 0.5.8 was run on 2024-11-27.

Both builds include 11 platforms. Cargo.toml lists 14 platforms as targets for documentation. The most recent build is missing x86_64-unknown-linux-gnu, the older build has that platform but is missing other platforms.

I don't see any information that docs.rs is limited to 11 platforms. But there is a very old mention that it's limited to 10 platforms: https://github.com/rust-windowing/winit/issues/1028#issuecomment-607882907

Inspect Cargo.toml's documentation targets and compare them with the two docs.rs build logs linked in the issue. Determine why x86_64-unknown-linux-gnu is omitted and verify the fix by confirming that the target appears in a subsequent docs.rs build.
