Remember that OS X goes to great lengths to hide 32 vs. 64 bit
distinctions; 32 bit OS X kernels were perfectly capable of running 64 bit
binaries on 64-bit CPUs, at least on Intel. So some of this comes down to
"Apple so decreed and it's much easier to play along than to try to make OS
X act differently". In particular, see how arch(1) works.
