Uhm, this is only relevant for the CI setup here which is still running on v1.7, no? What you're trying to fix?

ygg precompiling stdlibs again here https://buildkite.com/julialang/yggdrasil/builds/22152#019838bf-fdab-4c5f-9ad6-92ed5fa9ed6e/614-626

That's in Yggdrasil, presumably at https://github.com/JuliaPackaging/Yggdrasil/blob/49837563d4e5e87132a651644181c6396bd7e32d/.buildkite/build.sh#L9, not here

I fixed that here and it didn't solve the problem https://github.com/JuliaPackaging/Yggdrasil/pull/11683/files#diff-877fafdf17962f8430a77bec7d7a680291a6ebeee5929c0cb0f815eed85c9c54R10

Is this still needed?

It's logically sound, but it didn't fix the issue I was seeing. It likely helps somewhere avoid re-precompiling stdlibs, just not sure where.
