Allow user to select between Nios2 R1 and R2. Since R1 and R2 are
not binary compatible, we cannot have a single kernel binary and
there is no point in having DT property for discerning these two.

The dtc dependency is missing, thus dtc is not built before it's invoked,
resulting in the following problem:
linux-2.6$ make 10m50_defconfig && make 10m50_devboard.dtb
[...]
scripts/kconfig/conf --silentoldconfig Kconfig
DTC arch/nios2/boot/10m50_devboard.dtb

The extra CFLAGS required for correct operation of the toolchain are not
propagated into the libgcc detection code. In case of the compiler from
poky sdk, these extra CFLAGS contain the location of compiler sysroot
(the --sysroot= option) and without this option, the location of libgcc
is not properly reported. Add the missing CFLAGS to address this issue.

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.
