ldso: Extend prelink support for all other achitectures
Update Arch specific part of the dynamic linker to the latest cahnges required by prelink: - Use _dl_loaded_modules->scope as global symbol scope - Pass the sym argument (or NULL) to the _dl_find_hash - Update _dl_parse, _dl_do_reloc, _dl_do_lazy_reloc and _dl_parse_relocation_information to reflect the change of the scope argument's type - Add the call to _dl_debug_lookup used for trace prelinking.
