I _think_ that it can be determined by the ELF arch/endianness right
now, but i can imagine something like:

	* boot block has compiled in MACHINE_ARCH.

	* wants to check kernel's MACHINE_ARCH.

	* if MACHINE_ARCH isn't in the kernel's notes, BB has to
          calculate it.  if not MD checking code could be kinda
          tedious.

Also, I can imagine in the future that it might not be so easy to tell
e.g. between mips and mips64 kernels (esp. if the latter are built
"n32" style, i.e. in 32-bit ELF).


if nothing else:

costs just about nothing, is "pretty" from a "symmetry" perspective.
