Can you fetch the branch again and try it. I fixed a few dependency issues.

What is the value of CONFIG_NIOS2_DTB_SOURCE? As patch 3 notes, it now
should not have any path.

If that's a problem, I could take the basename to strip the path, but
then sub directories wouldn't work either.

BTW, next up, I want to consolidate the config variables for built-in dtbs.
