Either the following configurations: ``` architectures: - build-on: amd64 build-for: amd64 - build-on: arm64 build-for: arm64 - build-on: armhf build-for: armhf - build-on: ppc64el build-for: ppc64el ``` ``` architectures: - amd64 - arm64 - armhf - ppc64el ``` will only trigger the amd64 build in the Snapcraft build service, recipes for reference: * https://github.com/brlin-tw/ffmpeg-cat/commit/36d166462e58d6fbc69fef33495ef606a617bdbe * https://github.com/brlin-tw/ffmpeg-cat/commit/c1468f6d1d2c132e0d36e1d11e5330e429450a85
