Anyone here with Rust compilation experience? I can get compiling Rust 1.72 started but it immediately hangs at this:
```
+ python3 ./x.py build
Building bootstrap
running: /home/matti/SFOS/rust/BUILD/rust-1.72.1-i686-unknown-linux-gnu/usr/bin/cargo build --manifest-path /home/matti/SFOS/rust/BUILD/rustc-1.72.1-src/src/bootstrap/Cargo.toml --verbose --verbose --frozen
```
