    PR22216, infinite loop in readelf process_symbol_table

    This should make readelf bombproof given a fuzzed DT_HASH.  Also
    removes a bogus check that would have resulted in wrong histograms.

        PR 22216
        * readelf.c (process_symbol_table): Check that DT_HASH symbol
        chains are only visited once, and report an error if not.  Display
        invalid symbol index if chain is out of range.  Use the same logic
        when calculating histograms rather than the PR 17531 fix.  Delete
        bogus check that chained index is less than number of buckets.
