Re: [OE-core] [PATCH v2 3/7] pseudo: fix for build with glibc-2.43

["Böszörményi Zoltán" <zboszor@gmail.com>]

The issue turns out to be with GNU tar, specifically this build:
https://koji.fedoraproject.org/koji/buildinfo?buildID=2924033

Manually downgrading to the previous build fixed the packaging problem:
https://koji.fedoraproject.org/koji/buildinfo?buildID=2917292

I reported it here:
