// Check that when depending on a precompiled module, we depend on the
// **top-level** module. Submodules don't have some information present (for
// example the path to the modulemap file) and depending on them might cause
// problems in the dependency scanner (e.g. generating empty `-fmodule-map-file=`
// arguments).
