Running make run-ci with multiple jobs, it is possible for the C++ linker
to be invoked while build-addons is running, this can result in intermittent
ENOENT failures when spawning nodeGyp. To prevent this, originally
provide a different name for the executable, and rename it to the correct
name only after the link completes successfully.

Fixes #22006. Kinda. Sorta.

Are we sure it's only a Mac thing? I think I saw something similar on Linux when I was working on canary. I fixed it with git clean - fdx

I'm -0 on this. IMHO it just adds complexity to workaround the crux of the issue.

IIRC, this is not mac-only but makefile-only - we have been seeing the executable being deleted back in the days when the addons were built in a loop in makefile instead of in the new JS scripts.

Oh, wait, we need an entire new CI since there were changes since the last one.

@nodejs/gyp @nodejs/node-gyp Would be great to get a second review on this one.

Aside: Should we really have separate gyp and node-gyp teams or should that be merged into a single team?

I agree with @refack, this is more of a workaround than a fix.

Even though this is clearly a workaround: is there any solution in sight for the actual issue? If not, I do not see any downside in doing this for now.

Any other options about that?

With two approvals, I will merge this (after fixing the typo) on, say, ... Friday? ...unless there are any objections.

I've found that #23733 will workaround this issue.
And that relanding #23255 #23156 will fix it, so I'm blocking this issue until we prove it's the only way.
