         It is imperative that we use a different dynamic symbol for the

         In the dynamic symbol table, the function symbol will have a value
         which is address of the function's .opd entry.

         Thus, we can not use that dynamic symbol for the EPLT relocation
         (if we did, the data in the .opd would reference itself rather
         than the actual address of the function).  Instead we have to use
         a new dynamic symbol which has the same value as the original global
         function symbol.

         We prefix the original symbol with a "." and use the new symbol in
         the EPLT relocation.  This new symbol has already been recorded in
         the symbol table, we just have to look it up and use it.

         We do not have such problems with static functions because we do
         not make their addresses in the dynamic symbol table point to
         the .opd entry.  Ultimately this should be safe since a static
         function can not be directly referenced outside of its shared
         library.
