I'm not following you - ARCH=ppc is a kernel thing, it doesn't have
anything to do with buildroot.

Don't set ARCH or KERNEL_ARCH on the buildroot command line, only use
it when you are compiling a kernel (outside buildroot).

Suit yourself, but buildroot with Xilinx/ARCH=ppc kernels works (I use
it myself).
