armhf build fails due to missing libfolks
see https://arm01.puri.sm/job/debs/job/deb-chatty-buster+ci-armhf/ - the libfolks build never worked: https://arm01.puri.sm/job/debs/job/deb-folks-buster+ci-armhf/8/console so if chatty needs that libfolks it either needs the folks build fixed or both removed:
