Description
Similar to https://github.com/rust-lang/cargo/pull/8500, but going a step further by saying that usually build scripts aren't being edited by users, and even when they are, are quick to compile regardless. Incremental compilation is a net-negative if you're only going to compile once (compare "incremental full" and "full" on https://perf.rust-lang.org/dashboard.html).
This was noted while trying to cut down benchmark times on perf.rust-lang.org.

Research direction
Review the related rust-lang/cargo#8500 pull request and the build-script compilation behavior in Cargo. Compare “incremental full” with “full” on perf.rust-lang.org; done means build scripts no longer use incremental compilation and the benchmark behavior reflects the intended reduction.
