nios2: enable "make defconfig"
Running "make defconfig" currently fails for nios2:
$ make ARCH=nios2 defconfig
scripts/kconfig/conf --defconfig Kconfig
***
*** Can't find default configuration "arch/nios2/defconfig"!
***
make[1]: *** [defconfig] Error 1
make: *** [defconfig] Error 2
Add a definition for KBUILD_DEFCONFIG to the nios2's main Makefile to enable
this make target.
