Does this mean that if the application links against -ldl and invokes
dlopen, a different dynamic linker implementation is used?


??? There is only one dynamic linker, which is ld.so.
If this is really true, then I don't understand why we need the indirection in _dl_open_hook.
Is there a way to get rid of those function pointers, or move _dl_open_hook into a RELRO section?
