[PATCH] arch/h8300: add a defconfig target

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Make the "defconfig" target valid for arch/h8300.  Currently
"make ARCH=h8300 defconfig" produces:

*** Can't find default configuration "arch/h8300/defconfig"!
../scripts/kconfig/Makefile:87: recipe for target 'defconfig' failed

By adding a value for KBUILD_DEFCONFIG, "make ARCH=h8300 defconfig"
successfully produces a kernel .config file:

*** Default configuration is based on 'edosk2674_defconfig'

This is useful for Kconfig editing/testing.
