2864 Hook called by the linker routine which adds symbols from an object

2867 and neutralize STO_SH5_ISA32 found on the symbol definition.

2870 this symbol and signal to the caller that no further processing is
2871 needed. But we don't have the index for this hash-table entry. We
2872 rely here on that the current entry is the first hash-entry with NULL,
2873 which seems brittle. Also, iterating over the hash-table to find that
2874 entry is a linear operation on the number of symbols in this input
2875 file, and this function should take constant time, so that's not good
2876 too. Only comfort is that DataLabel references should only be found in
2877 hand-written assembly code and thus be rare. FIXME: Talk maintainers
2878 into adding an option to elf_add_symbol_hook (preferably) for the index
