I don't know the difference of ${arch} and ${karch} usage on amd, but
if we have complete binary compatibility among the same MACHINE_ARCH

In SunOS, "kernel architecture" was the term used to distinguish sun4, sun4c, sun4m, etc. Presumably, that's what amd's "karch" represents. That's why I say it's analogous to hw.machine.
