Similar to #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.
