Previously, this would change the test output when RUSTUP_HOME was set: ``` ---- [ui] ui/issues/issue-49851/compiler-builtins-error.rs stdout ---- diff of stderr: 1 error[E0463]: can't find crate for `core` 2 | 3 = note: the `thumbv7em-none-eabihf` target may not be installed + = help: consider downloading the target with `rustup target add thumbv7em-none-eabihf` 4 5 error: aborting due to previous error 6 ``` Originally, I fixed it by explicitly unsetting RUSTUP_HOME in compiletest. Then I realized that almost no one has RUSTUP_HOME set, since rustup doesn't set it itself; although it does set RUST_RECURSION_COUNT whenever it launches a proxy. Then it was pointed out that this runtime check doesn't really make sense and it's fine to make it unconditional.
