This fixes https://github.com/rust-lang/rust/issues/151813 that miscompiled rustc self on [sparcv9-sun-solaris](https://doc.rust-lang.org/stable/rustc/platform-support/solaris.html) which is Tier 2 with Host Tools for Rust.

This doesn't stop distributing from the Rust crossing building CI, but it does stop building on the spracv9 host.
