False positive error can't find crate for test despite check.allTargets unset

[widlarizer]

"rust-analyzer.check.allTargets": false is insufficient to avoid error[E0463]: can't find crate for `test` in a no_std project with a custom build of the Rust toolchain.

• rust-analyzer 1.67.0-dev (72d0f607166 2023-02-08)
• same version cargo and rustc
• VS Code extension installed from official version rust-lang.rust-analyzer-0.4.1404@linux-x64.vsix

Please suggest additional information that I could provide. cargo check works just fine with this custom toolchain, so the extension must be calling cargo test or something similar, which is why I tried setting rust-analyzer.check.allTargets to false as per #11982

I ran into the same problem in a no_std project. Searching for --all-targets shows

rust-analyzer/crates/rust-analyzer/src/handlers.rs

Lines 748 to 753 in f1e51af

	cargo_args: vec![
	cmd.to_string(),
	"--package".to_string(),
	spec.package.clone(),
	"--all-targets".to_string(),
	],

in the code which includes --all-targets in an invocation to cargo check without consulting the setting.

The code for FlyCheck does respect the setting:

rust-analyzer/crates/flycheck/src/lib.rs

Lines 327 to 329 in f1e51af

	if *all_targets {
	cmd.arg("--all-targets");
	}

This spot also doesn't respect the setting, but I can't tell if it is related:

rust-analyzer/crates/project-model/src/build_scripts.rs

Line 75 in f1e51af

cmd.arg("--all-targets");
