PING [PATCH] elf: Keep only one '@' for undefined versioned symbols

Hi H.J.

>> The symbol string table in the .symtab section is optional.  Keep only
>> one '@' for undefined versioned symbols, which are defined in shared
>> objects, in the symbol string table.  Update "nm -D" to display only
>> one '@' for undefined versioned symbols.

Approved - please apply - but ... please could you also add a sentance
or two to the description of nm's -D option in binutils.texi making it
clear that one @ symbol means either a hidden or an undefined symbol.
