handle undefined extern vars in output_in_order
* cgraphunit.c (cgraph_order_sort_kind): New entry ORDER_VAR_UNDEF.
(output_in_order): Loop over undefined variables too. Output them
via assemble_undefined_decl. Skip variables that correspond to hard
registers or have value-exprs.
* varpool.c (symbol_table::output_variables): Handle undefined
variables together with defined ones.
