Hmm, isn't this the case that end up using `EXPORTAS` already, since https://github.com/llvm/llvm-project/pull/98229? Would it be clearer to test a case here, where you'd have a separate `efunc` entry, so that it shows that even if we have the target exported, we'd still use the `EXPORTAS` type instead of weak aliases?
