Using rustc/Cargo.toml would load a crate that depends on ~all the other crates, which might give better test coverage.

Hm, Ralf's suggestion with using rustc-the-crate makes sense to me.

Switched to the rustc crate.

Thanks, the changes themselves look good to me, just a tiny drive-by nit on pre-existing distcheck dir names because they made it even more confusing...

-            .current_dir(&src_dir)
-            .run(builder);
-    }
+        distcheck_plain_source_tarball(builder, &root_dir.join("distcheck-plain-src"));


Suggestion: could you add a comment that this is rustc-src while the one below is rust-src? And even maybe change the dir name here to distcheck-rustc-src? I know this is historical, but rustc-src and rust-src are two incredible names that are totally not confusing.

Or maybe just change their dir names to match the actual dist component name, because I find that diverging here introduces even more *-srcs, and it really confused me. As in, distcheck-plain-src checks rustc-src, and distcheck-src checks rust-src...

Feel free to r=me after the dir name nit
