    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.
