JS-only builds now require that a suitable rustc and cargo be found at configure time (bug 1444141, currently on inbound). The version requirements are identical to Gecko's version requirements (Rust 1.27.0 at the time of this writing) and will be bumped in tandem with Gecko's version requirement bumps.
Note that *no* Rust code is being built in the JS engine/shell at this time; we are adding the requirement first to make development of Rust-requiring projects easier (e.g. bug 1469027 for cranelift support for wasm).
