I think it's the CROSS_BUILD_TESTING that's causing the problem.  It's
trying to run the x86 cross-tools during the native install.  Try
replacing that with MAKEOBJDIRPREFIX=/usr/obj/arm.armv6.  I'm not sure
that'll work, I've never tried to do what you're doing... I do the
install on the same machine as the cross-builds, using

 make installworld TARGET_ARCH=armv6 DESTDIR=/path/to/nfsroot

and likewise for installkernel but with KERNCONF added.
