nios2: basic build, non-functional

Browse source 
Basic build framework for Nios2. Everything is stubbed out,
we just want to have a build going so that we can start to
parallelize implementation tasks.

This patch is not intended to be functional, but should be
able to produce a binary for all the nanokernel-based
sanity checks.
