Error when running libc-test: `cfg(target_vendor)` is experimental

[farao]

I'm not sure if the problem lies in libc's libc-test or in ctest2:

--- stderr
error: cfg(target_vendor) is experimental and subject to change (see issue #29718)
--> /target/x86_64-unknown-l4re-uclibc/debug/build/libc-test-8ad8f4765d91ee28/out/src-hotfix/primitives.rs:23:13

23 | not(target_vendor = "apple"),

I try to get the libc-test suite running for a new operating system (l4re). I have a working freshly built toolchain for it and I adapted libc-test/build.rs for the new OS. Any idea where this could come from? target_vendor has been stable for ages and my built toolchain is based on a quite new state what the output of libc-test also shows:

rust version: 1.86.0-nightly

The command I ran was: CFLAGS="-nostdlib -nostdinc -I... -L..." cargo +l4re test --target x86_64-unknown-l4re-uclibc

I have no idea why this happens, but it should have been fixed by #4282.

Confirmed, thanks (and sorry for apparently not being on the newest state)!

Well I did that change after you opened the issue so it was the latest state at the time :) thanks for reporting!
