Bug 1321691 - Suggest boostrap if configure fails to find rust. r=chmanchester Now that `./mach boostrap` installs rustup, suggest this if configure fails to find the toolchain when building with --enable-rust. Also point out https://rustup.rs/ for those who want more control. MozReview-Commit-ID: 8JIbERfz12f
