Looking at this more closely, I see that we do in fact already call
define_in_output_data() to create STB_LOCAL symbols (e.g.,
_GLOBAL_OFFSET_TABLE, _DYNAMIC).

I'm thinking the right thing to do here is to pass the binding to
Symbol_table::define_special_symbol(). If the binding is STB_LOCAL, it
should create a new Sized_symbol and add it to the forced_locals_ list
instead of to the global symbol table.
