MACHINE_ARCH is the machine you are building on very early in the build. It is soon set to TARGET_ARCH. BUILD_ARCH retains the initial value of MACHINE_ARCH. This check makes sure that you set TARGET correctly (which causes TARGET_ARCH to be set to the right value). You can see my blog for complete instructions that work back on both 7.x and -current (except for the NSLU part): http://bsdimp.blogspot.com/2008/08/nslu2-support-committed-to-freebsdarm.html This was how I built NFS root for my NSLU2. Earlier posts talk about how to build root on a CF. I made one small correction...
