One thing that would help in better supporting NIOS is if we could add
support for building linux-user tests for it in test/tcg. For this we
need a distribution that ships a decent cross compiler or create a
docker recipe that packages it up so we can build and run the tests.
Are you just building GCC straight from source or can you point to a
recommended location for a decent packaged gcc?
