Compiling lldb, in a cmake sub-project that compiles with visibility
hidden, will generate a "cannot export hidden symbol" error because we
require default visibility. Even though we export using
-Wl,-exported_symbols_list,liblldb.exports, if each .cpp file is
compiled with -fvisibility=hidden, then you'll get this warning and
linking will fail. Essentially -exported_symbols_list is not strong
enough to reverse the -fvisibility=hidden.
