        elf: Don't set its DT_VERSYM entry for unversioned symbol
    
    ld no longer assigns version index 1 to unversioned defined symbol.
    For libmachuser.so, "objdump --dynamic-syms" reports:
    
    0000dd30  w   DF .text  000000f8              processor_start
    
    instead of
    
    0000dd30  w   DF .text  000000f8 (Base)       processor_start
    
    Also allow NF == 6 for weak unversioned dynamic symbols.  This fixes BZ
    33650.
