Great that you got the tests to run; however this ‘check’ phase doesn’t
respect the ‘--without-tests’ package transformation.  The snippet below
should do.

--8<---------------cut here---------------start------------->8---
(lambda* (#:key tests? #:allow-other-keys)
  (when tests?
    (invoke "./libphonenumber_test")))
--8<---------------cut here---------------end--------------->8---

For some reason the build is still not reproducible for me; I ran
diffoscope on the two outputs, and it produced 120 MB worth of output…

Maybe a third person could test if the build is reproducible.
