description:
Use .org directive to fix disklabel location instead of hand calculation.
If the code size before disklabel is less, zero is filled automatically.
If the code size before disklabel is exceeded, assembler stops with error.
Note that this changes a padding word in the current output binary from
a NOP instruction to zero but there are no functional changes.
