That test case is currently testing two things:

1. What happens when a program has a module with the same name as
    a browser module (its original purpose).

2. --linkage static

(1) is still worthwhile. (2) is increasingly unsupported by most
operating systems out-of-the-box, so I think we could dispense with it.

That's fine.
