Looking quickly at the diffoscope output, it appears that some generated files are not ordered in the same way.

One way to observe it is with current glibc in oe-core master: alex@Zen2:/srv/storage/alex/yocto/build-64/tmp/work/x86-64-v3-poky-linux/glibc/2.42+git/sources/glibc-2.42+git/posix$ gawk -f ../scripts/gen-posix-conf-vars.awk posix-conf-vars.list|less (run on different hosts to get the varying gawk versions, or use gawk-native vs host gawk, and you'll see the reported reproducibility difference directly) 103416 5 ross.burton 2025-11-27 16:09:08 +0000 Fixed in oe-core c5bbf0a60b1 (gawk: use native gawk when building glibc and grub, 2025-11-21).
