    Don't issue an error if DT_PLTRELSZ is missing
    
    A shared object doesn't need PLT if there are no PLT relocations.  It
    shouldn't be an error if DT_PLTRELSZ is missing.
    
    	[BZ #18410]
    	* elf/dl-reloc.c (_dl_relocate_object): Don't issue an error
    	for missing DT_PLTRELSZ.
