There are a few tier-3 targets that have ABI descriptors in their target_env.

compiler/rustc_target/src/spec/armv6_unknown_freebsd.rs:13:        target_env: "gnueabihf".to_string(),
compiler/rustc_target/src/spec/armv6_unknown_netbsd_eabihf.rs:14:        target_env: "eabihf".to_string(),
compiler/rustc_target/src/spec/armv7_unknown_freebsd.rs:13:        target_env: "gnueabihf".to_string(),
compiler/rustc_target/src/spec/armv7_unknown_netbsd_eabihf.rs:13:        target_env: "eabihf".to_string(),

The precedent from other targets is that these should be just "gnu" or an empty string. This came up in the RFC for target_abi, rust-lang/rfcs#2992 (comment), where I'd expect these targets will have target_abi: "eabihf".

```
