From: Alexander Kanavin <[email protected]> Please see https://bugzilla.yoctoproject.org/show_bug.cgi?id=16087 for the tricky, unpleasant details.
The summary of the issue: >From Fedora 42 onwards, the --rosegment argument is passed to the linker by default when building native binaries. This triggers re-arrangement of sections by patchelf, resulting in binaries which are loaded incorrectly by older kernel versions. These "contaminated" native binaries end up in sstate and cause build failures when they are used on older distros such as AlmaLinux 8 & 9 or Rocky Linux 8 & 9.
