Rollup merge of #126720 - Rejyr:migrate-branch-protection-rmake, r=jieyouxu 
Ignore `branch-protection-check-IBT` run-make test

The old Makefile implementation (#110304) had an improper comparison which caused the test to never run. However, both the updated Makefile implementation and the rmake implementation fail (missing `.note.gnu.property`). This could be a bug in the original implementation or test flakiness.

Edit: Manually recreating the test case shows that `.note.gnu.property` does not appear in nightly.
```rust
// main.rs
fn main() {
    println!("hello world");
}
```
```sh
$ rustc +nightly -V
rustc 1.81.0-nightly (c1b336cb6 2024-06-21)
$ rustc +stable -V
rustc 1.79.0 (129f3b996 2024-06-10)
```
```sh
$ rustc +nightly -Zcf-protection=branch -Clink-args=-nostartfiles -Csave-temps "-L$PWD" main.rs -o main
$ llvm-readobj --elf-output-style=GNU -nW main

Compiling without the other flags still does not show `.note.gnu.property`.

Compiling on stable shows `.note.gnu.property`.

README.md

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
