 Look at this:

 The `clang_darwin` target indeed is being completely skipped for some
 reason, because make determines that there is nothing to be done.
 Obviously wrong. Afterwards, the `clang_macho_embedded` target is built
 correctly.

 So... the question seems to be why the `clang_darwin` target is not built
 correctly/no object files being generated in `ProjObjRoot`.
