OUT_DIRs value has changed in nightly.

[ltratt]

This was changed in rust-lang/cargo#17272. This might change back for all I know, but at least for now this unbreaks things.

[Pavel-Durov]

We could do something like:

pub fn full_cargo_profile() -> String {
    let target_dir = target_dir();
    let out_dir = PathBuf::from(env!("OUT_DIR"));
    out_dir
        .ancestors()
        .find(|p| p.parent() == Some(target_dir.as_path()))
        .and_then(|p| p.file_name())
        .and_then(|n| n.to_str())
}

Way more code, but then we don't need to rely on dir layout

[Pavel-Durov]

We can use cargo_metadata for that:

Suggested change

	}
	pub fn target_dir() -> PathBuf {
	let cargo = std::env::var("CARGO").unwrap_or_else(|_| "cargo".to_owned());
	let metadata = cargo_metadata::MetadataCommand::new()
	.cargo_path(cargo)
	.no_deps()
	.exec()
	.expect("failed to run `cargo metadata`");
	metadata.target_directory.into_std_path_buf().clone()
	}

Suggested change

	pub fn full_cargo_profile() -> String {
	let out_dir = PathBuf::from(std::env::var("OUT_DIR").unwrap());
	out_dir
	.strip_prefix(ykbuild::target_dir())
	.expect("OUT_DIR is not inside cargo's target directory")
	.components()
	.next()
	.map(|x| x.as_os_str().to_str().unwrap())
	.unwrap()
	.to_owned()
	}

Right now, I don't think we can work around this problem other than by setting the CARGO_UNSTABLE_BUILD_DIR_NEW_LAYOUT=false variable, so I'm closing this PR.
