That's expected: this derivation does not produce any outputs.
Assuming you intended to write (%current-system) to test.txt, you can do
something along these lines:
(computed-file "test.txt"
#~(call-with-output-file #$output
(lambda (port)
(format port #$(%current-system)))))
So I think this is not-a-bug. WDYT?
