it's pointless and causes an unnecessary delay.
what's worse, we wouldn't actually know whether we found a compatible
(gnu) readlink, so the fallback would never get activated. this would be
the case on macos (the problem wasn't noticed so far, because on macos
we build a bundle which doesn't need the wrapper in the first place).
