When processing a dynamic relocation for a weak undefined symbol, it is
not an error if the symbol is not found (such a symbol should resolve
to zero). The current code doesn't make a special case of this; it sets
the value to zero *after* the symbol lookup. That's OK when the binary
uses the legacy dynamic symbol table (DT_HASH format), because undefined
symbols are present in it. However, things will break when we switch to
the newer DT_GNU_HASH format which doesn't include them.
Update the code to prepare the DT_GNU_HASH support.
