Currently the environment (the copr-rpmbuild wrapper script) guards that mock
doesn't run longer than expected (it is not a mock built-in timeout).
Not saying it is not possible to do this in Copr, but it wouldn't be an easy
thing to implement. Much easier would be something like --timeout 3600
--timeout-armhfp=7200, or --timeout-forcearch=300%, or something alike.
