It uses the internal dependency tree to generate the *.out file, but
does not artificially limit what that tree might rebuild.

It does not do the implied "make" that "make check" does, if that's what
you're asking.  It literally just reruns the one test - rebuilding the
test itself if needed, but not rebuilding libc.so because there's no
dependency on it.

So you'd need to run "make && make onetest t=..." if you want to rebuild
libc.so first.

Let the bikeshedding begin!  :-)
