This is a fly by comment as I'm not at a computer at the moment to investigate in detail, but this does not feel correct. By definition test-ci-js should not require a native compiler -- those tests should be in test-ci-native. I can see a few lines above have test/ffi/.buildstamp as a requisite for test-ci-native, so my assumption would be that the ffi testsuite has been misclassified into CI_JS_SUITES instead of CI_NATIVE_SUITES.
