   Hook called by the linker routine which adds symbols from an object
   file.  We must make indirect symbols for undefined symbols marked with
   STT_DATALABEL, so relocations passing them will pick up that attribute
   and neutralize STO_SH5_ISA32 found on the symbol definition.
 
   There is a problem, though: We want to fill in the hash-table entry for
   this symbol and signal to the caller that no further processing is
   needed.  But we don't have the index for this hash-table entry.  We
   rely here on that the current entry is the first hash-entry with NULL,
   which seems brittle.  Also, iterating over the hash-table to find that
   entry is a linear operation on the number of symbols in this input
   file, and this function should take constant time, so that's not good
   too.  Only comfort is that DataLabel references should only be found in
   hand-written assembly code and thus be rare.  FIXME: Talk maintainers
   into adding an option to elf_add_symbol_hook (preferably) for the index
   or the hash entry, alternatively adding the index to Elf_Internal_Sym
   (not so good).  */
