Alice Ryhl 5e5a29bd54 rust: SHADOW_CALL_STACK is incompatible with Rust ... commit f126745da8 upstream. When using the shadow call stack sanitizer, all code must be compiled with the -ffixed-x18 flag, but this flag is not currently being passed to Rust. This results in crashes that are extremely difficult to debug. To ensure that nobody else has to go through the same debugging session that I had to, prevent configurations that enable both SHADOW_CALL_STACK and RUST. It is rather common for people to backport 724a75ac95 ("arm64: rust: Enable Rust support for AArch64"), so I recommend applying this fix all the way back to 6.1.
