I noticed this build warning go by in my build-spew:
warning: Cannot set
RUSTC_BOOTSTRAP=1from build script ofqcms v0.2.0 (gfx/qcms).note: Crates cannot set
RUSTC_BOOTSTRAPthemselves, as doing so would subvert the stability guarantees of Rust for your project.
Looks like the RUSTC_BOOTSTRAP=1 line is here:
https://searchfox.org/mozilla-central/diff/0f0c9a9a0c08caf88e305875e1e6376f4a9689a7/gfx/qcms/build.rs#4
...and it was added in the first version of this file in bug 1666057. (It was put behind a guard in bug 1702080, though I'm not sure that makes a difference here.)
Is this warning telling us something useful? Do we actually need or care about having RUSTC_BOOTSTRAP here?

In bug 1670538 we started setting RUSTC_BOOTSTRAP for Rust 1.50+
Rust 1.50+ gives a warning if we set in build.rs so don't.
