Seems like a palatable workaround. I think you may need to enforce it once or twice to have teeth but it’s not unheard of. I heard that you can’t release GPL software on the Apple Store due to similar issues.
That's assuming the courts agree. I haven't read the linker code, but it's very possible that whatever code the linker includes would not be found "creative" enough to be copyrightable. In contrast, libgcc, which gcc links into generated binaries, contains non-trivial routines[0].

I really don't think that is the point. This seem to be targeted at scaring legal departments to ease over the process of having corps fork over the money for something they might think could be obtained for free.
