I think you should add
llvm-tools(-preview)component.Mark-Simulacrum commentedon May 26, 2020
Yes, this is expected fallout from a recent change. Please let me know if it's causing serious problems though, it's plausible we can find an alternative way of achieving the goals of the PR that broke this.
The rustc-dev component which you need for this isn't shipped on stable so this isn't a stable-to-nightly regression.

Thanks!
fix: Resolve linker issues on linux by adding llvm-tools rust component
