testing issue body

[Mark-Simulacrum]

Moved from rust-lang/rust-clippy#4267

#61861 was merged in #61962, since then Rustfmt fails to build when cross compiling which is the case for almost all non Tier 1 platforms.
Clippy and RLS are failing with similar error.

Error on aarch64-unknown-linux-gnu:
