Not working on relibc #5268

Relibc has an unusual structure: Inside the src dir there are multiple dirs which each contain a regular cargo project with Cargo.toml and src/lib.rs, but also a ./mod.rs, which is used from the top-level src/lib.rs. For these mod.rs ide features are not working.

Yeah, this does not work because we currently softly assume that modules can't point across crates (we used this to avoid checking each mod foo; in stdlib, when a user crates new file in src). The solution here is to put all of the crates into a single FileSet, (instead of creating a fileset per crate). At the moment, we infer file sets from Cargo.toml though, and don't have a way to override them.
