Currently, "make defconfig" is only supported for sandbox and x86. I set KBUILD_DEFCONFIG to support "make defconfig" where I was able to find a suitable one. nios2 and openrisc have a single generic_defconfig, so it is definitely good for KBUILD_DEFCONFIG. For arm, mips, I assume qemu is a preferred choice over a real board. blackfin has only one defconfig. Since it is inactive (it is gone in Linux), so no more defconfig will come in. I am not sure about ppc and riscv, so I did not touch them.
