Combine linker scripts for single volume and multi-volume ECKD dumpers to avoid duplicating. Use C preprocessor to define conditional symbols. Cleanup the generic stage2 linker script(stage2.lds). Since it is still used for FBA and TAPE dumpers (fba2dump and tape2dump) the .stage2dump.tail section should be preserved.
