The linker expands the PLIT definition into individual entries in a table.
An entry is created for each overlay symbol as shown in
page 5-10. The redirection function calls the PLIT table for overlays 1 and
2 (Table 5-2). For each entry, the linker replaces the generic assembly
instructions with specific instructions (where applicable).
