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 ff872dc349 build: rename non-generated linker scripts to .ld extension
Avoids confusion with .gitignore rules, which were inadequate to
cover all the places where these files are found. At least in
VIM, these files are now syntax highlighted correctly.

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.
