Summary: We need to handle the MCSA_LGlobal case in emitSymbolAttribute for functions marked internal in the IR so that the appropriate storage class is emitted on the function descriptor csect. As part of this we need to make sure that external labels are not emitted into the symbol table, so we don't emit the descriptor label in the object writing path.
