Description of change

The findAccessibleSync() function is in the local util module instead of Node.js' builtin util module.

Refs: nodejs/node#50493 (comment)

---

Existing tests should cover this, but only on AIX or z/OS, neither of which are available on GitHub Actions (and neither of those OSes are a supported platform for running a self-hosted runner).

Took me a while to figure out how to get citgm-smoker-nobuild to run with this PR[1]:

• Fails with [email protected]: https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker-nobuild/1539/nodes=aix72-ppc64/console
• Passes with 4c110b9 (this PR): https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker-nobuild/1544/nodes=aix72-ppc64/console

[1]: I had to use

citgm --sha 4c110b952222501b677585e230932b140767168f node-gyp

for some reason citgm fails to find tests if run with

citgm richardlau/node-gyp#aix

You've got good eyes, I did NOT see the ./ there.

That's because it was missing 😆.

Thank you @richardlau! I've published [email protected] and will release it in [email protected] and get a new Node.js PR open as well.
