Rust for Linux notification group

Github Label: O-rfl
Ping command: @rustbot ping rfl

This list will be used to notify Rust for Linux (RfL) maintainers when the compiler or the standard library changes in a way that would break Rust for Linux, since it depends on several unstable flags and features. The RfL maintainers should then ideally provide support for resolving the breakage or decide to temporarily accept the breakage and unblock CI by temporarily removing the RfL CI jobs.

The group also has an associated Zulip stream (#rust-for-linux) where people can go to ask questions and discuss topics related to Rust for Linux.

If you are interested in participating, please sign up for the Rust for Linux group on Zulip!
