The tools/ directory already does this for a tons of things. Its where
I ended up placing some API I tested a long time ago when I wanted to
test it in userspace, and provide the unit test in userspace (for my
linker table patches).

Should be relatively easy if the tools directory used. Yes, there is
an inherent risk of duplication, but that was decided long ago.
