opensuse-tumbleweed lacks awk by default

https://gitlab.com/nbdkit/libnbd/-/jobs/4878710589 for opensuse-tumbleweed failed with:

configure: creating ./config.status
config.status: creating podwrapper.pl
./config.status: line 1496: awk: command not found

but lcitool/facts/mappings.yml does not list awk as a package worth demanding for some projects
