LLD previously used to handle dynamic lists and version scripts in the exact same way, even though they have very different semantics for shared libraries and subtly different semantics for executables. r315114 untangled their semantics for executables (building on previous work to correct their semantics for shared libraries). With that change, dynamic lists won't set the default version to VER_NDX_LOCAL, and so resetting the version to VER_NDX_GLOBAL in scanShlibUndefined is unnecessary. This was causing an issue because version scripts containing `local: *` work by setting the default version to VER_NDX_LOCAL, but scanShlibUndefined would override this default, and therefore symbols which should have been local would end up in the dynamic symbol table, which differs from both bfd and gold's behavior. gold silently keeps the symbol hidden in such a scenario, whereas bfd issues an error. I prefer bfd's behavior and plan to implement that in LLD in a follow-up (and the test case added here will be updated accordingly).
