This change removes the CI check that applies to freebsd version cfg. This is causing problems where the freebsd version defaults to 11 when CI is not enabled, some types may be incorrect on a > 11 system, and compilation failures ensue. A concrete example is libc::dev_t. This was defaulting to u32 on my FreeBSD 13-STABLE desktop, when it should have been u64. I couldn't compile anything that uses libc::devname_r as a result.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @Amanieu (or someone else) soon. Please see the contribution instructions for more information. |

Note that there's a previous attempt about that, #2581, and it was reverted as it causes an unwanted regression. See the discussion on the mentioned PR. |
This means we're missing something like #[cfg_attr(all(target_os = "freebsd", freebsd11), link_name = "devname_r@FBSD_1.0")]I really think we should add versioned symbols to ALL functions already. |

I'm going to close this with the above reason, we should discuss how we treat these cfgs first, I think. |
