2905 Hook called by the linker routine which adds symbols from an object

2907 STT_DATALABEL, so relocations passing them will pick up that attribute
2908 and neutralize STO_SH5_ISA32 found on the symbol definition.
2909
2910 There is a problem, though: We want to fill in the hash-table entry for
2911 this symbol and signal to the caller that no further processing is
2912 needed. But we don't have the index for this hash-table entry. We
2913 rely here on that the current entry is the first hash-entry with NULL,
2914 which seems brittle. Also, iterating over the hash-table to find that
2915 entry is a linear operation on the number of symbols in this input
2916 file, and this function should take constant time, so that's not good
2917 too. Only comfort is that DataLabel references should only be found in
2918 hand-written assembly code and thus be rare. FIXME: Talk maintainers
2919 into adding an option to elf_add_symbol_hook (preferably) for the index
