: on m68k, MACHINE describes a ... say, mainboard family (eg, Amiga).
: MACHINE_ARCH is m68k

"Different wavelengths."  I was clarifying that even for V9 SPARC binaries
on sparc64, it's still using the same binary format and layout (whereas on
m68k, the a.out header and format are identical no matter whether you use
68020 or 68060 instructions).
