Reported by Aakash Sen Sharma (@Shinyzenith) at https://rust-for-linux.zulipchat.com/#narrow/stream/291565-Help/topic/Build.20errors/near/364313442.
Requires LLVM >= 16 to reproduce. bindgen 0.62.0 fixes it: rust-lang/rust-bindgen#2488, rust-lang/rust-bindgen#2319 (thanks @cuviper for the pointer!).
