Ever since I added s390x support to zlib the package has been failing to build on the buildd, apparently because it doesn't support s390x binaries. This hasn't been a showstopper since the package seems to be getting built somehow but it is a bit worrying seeing the failed build report and will create more work for porters.
Is there anything I can do to stop the build being tried on unsuitable machines? -- "You grabbed my hand and we fell into it, like a daydream - or a fever."
