   Hook called by the linker routine which adds symbols from an object
2809
   file.  We must make indirect symbols for undefined symbols marked with
2810
   STT_DATALABEL, so relocations passing them will pick up that attribute
2811
   and neutralize STO_SH5_ISA32 found on the symbol definition.
2812
 
2813
   There is a problem, though: We want to fill in the hash-table entry for
2814
   this symbol and signal to the caller that no further processing is
2815
   needed.  But we don't have the index for this hash-table entry.  We
2816
   rely here on that the current entry is the first hash-entry with NULL,
2817
   which seems brittle.  Also, iterating over the hash-table to find that
2818
   entry is a linear operation on the number of symbols in this input
2819
   file, and this function should take constant time, so that's not good
2820
   too.  Only comfort is that DataLabel references should only be found in
2821
   hand-written assembly code and thus be rare.  FIXME: Talk maintainers
2822
   into adding an option to elf_add_symbol_hook (preferably) for the index
2823
   or the hash entry, alternatively adding the index to Elf_Internal_Sym
2824
   (not so good).  */
