gold patch committed: Adjust symbols in GNU hash table

[Ian Lance Taylor]

The last elflint problem: some undefined symbols were winding up in
the GNU hash table.  This patch changes the selection to 1) always add
symbols whose value is needed; 2) otherwise, don't add symbols defined
in a dynamic object or forced local.  Committed to mainline.
