<pre>Currently lld behaves as if --allow-shlib-undefined is given, and there's no
way to check whether undefined symbols in DSOs can be resolved or not.
The lack of the option could result in a bad user experience. For example,
imagine that a user forgot to implement some function in a DSO. The DSO links
fine. And all executables that uses the DSO link fine with lld. But the
executables would fail at run-time because the symbol cannot be resolved by the
dynamic linker. Even worse, they don't always fail at start-up time because of
PLT entries are resolved lazily.
Maybe we should evaluate the impact of implementing --no-allow-shlib-undefined.
If it can be implemented easily, we probably should do that.</pre>
