2698 Hook called by the linker routine which adds symbols from an object

2700 STT_DATALABEL, so relocations passing them will pick up that attribute
2701 and neutralize STO_SH5_ISA32 found on the symbol definition.
2702
2703 There is a problem, though: We want to fill in the hash-table entry for
2704 this symbol and signal to the caller that no further processing is
2705 needed. But we don't have the index for this hash-table entry. We
2706 rely here on that the current entry is the first hash-entry with NULL,
2707 which seems brittle. Also, iterating over the hash-table to find that
2708 entry is a linear operation on the number of symbols in this input
2709 file, and this function should take constant time, so that's not good
2710 too. Only comfort is that DataLabel references should only be found in
2711 hand-written assembly code and thus be rare. FIXME: Talk maintainers
2712 into adding an option to elf_add_symbol_hook (preferably) for the index
