Introduce DL_LOOKUP_FOR_RELOCATE flag for _dl_lookup_symbol_x
This will allow changes in dependency processing during non-lazy binding, for more precise processing of NODELETE objects: During initial relocation in dlopen, the fate of NODELETE objects is still unclear, so objects which are depended upon by NODELETE objects cannot immediately be marked as NODELETE.
