It is most likely false-sharing on multiconfig. Now if we look for
"[stamp-extra-info]" in the source-tree we will find several
combinations.

"${DISTRO}-${DISTRO_ARCH}"
"${DISTRO}-${MACHINE}"
"${MACHINE}-${DISTRO}"
"${DISTRO}"

And possibly several tasks that should have an extra-stamp but do not.
Avoiding multiconfig is a very good idea, not just for CI ;).
