However, during LD_STAGE 2, the build fails with "multiple definition" errors because the linker hits identical symbols in both my scheduler's object file and kern_runq.o.

You haven't given any examples of name collisions.
Why don't you just give your functions different names?

If you need to "override" some functions in kern_runq, something is wrong
(where "something" could mean the scheduler abstraction in NetBSD or your
design, or anything else).

Please provide more details of what you are trying to do.
