Rust no longer has support for JIT compilation, so it doesn't currently require a PaX MPROTECT exception. The extended attributes are preferred over modifying the binaries so it's not actually going to work on most systems like this anyway. If JIT compilation ends up being supported again, it should handle this by *always* applying the exception via an extended attribute without performing auto-detection of PaX on the host. The `paxctl` tool is only necessary with the older method involving modifying the ELF binary.
