Andrew Boie 2d5645e57a nios2: add minimal crt0.S
At the moment this just jumps into prep_c, with comments left
on other things that need to be done. Having this here ensures that
the early boot code isn't discarded by gc-sections.

vector_table.c removed, it isn't the right approach for this CPU.
Proper method for initializing reset and exception vectors still
being investigated.

Andrew Boie 9433895954 nios2: basic build, non-functional
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.
