1914e470e3 build: copy config.{guess,sub} post autogen in zmq package (fanquake)
Pull request description:
Otherwise our config.guess and config.sub will be copied over. This problem has been masked by the fact that modern systems ship with versions that recognise all the triplets we use (namely arm64-apple-darwin). However building on ubuntu 20.04 surfaces the issue.
Fixes#26420.
