nios2: Add new architecture
This commit adds very basic support to build for the Nios II architecture. Toolchain support is still missing and instead we need to use an external custom toolchain. Notice that this architecture had been previously removed in Buildroot 2010.05-rc1 release (as explained in the CHANGES file) and this commit adds it back.

Say 'y' if you want to generate the toolchain with crosstool-NG
