add missing s390x target feature to std detect test Fix an oversight from https://github.com/rust-lang/rust/pull/145656, where the `is_s390x_feature_detected!` macro and some target features were stabilized, but other target features remain unstable under a new target feature name. I tested this locally using a `stage1` build on the test file with the `s390x-unknown-linux-gnu` target. cc ```@uweigand``` r? ```@Amanieu``` (or whoever really) |
