--- Comment #16 from Andreas Schwab <schwab@linux-m68k.org> ---
If you want to build for old systems you need to use the old tools from those
old systems and the output will still work on newer systems (backward
compatiblity).  New tools are using new features as they are available (no
forward compatibility).
