Help get me oriented and I'll start grinding through this.

What values of TARGET_ARCH should be supported?

Right now, there are ARCH values of arm and armeb.
Should there be armv6eb?  armv7?

I'm also unclear on the distinction between make's MACHINE_ARCH
and uname -p; are these supposed to be the same?  If so, shouldn't
make be using a sysctl instead of a hard-coded value?
