The behavior and failure is indeed pretty consistent accross those
architectures:

 - arm64: https://travis-ci.org/clebergnu/qemu/jobs/621238740#L4217
 - ppc64le: https://travis-ci.org/clebergnu/qemu/jobs/621238741#L4252
 - s390x: https://travis-ci.org/clebergnu/qemu/jobs/621238742#L4265

And with this, 060 gets skipped properly:

 - arm64: https://travis-ci.org/clebergnu/qemu/jobs/621248591#L4202
 - ppc64le: https://travis-ci.org/clebergnu/qemu/jobs/621248592#L4236
 - s390x: https://travis-ci.org/clebergnu/qemu/jobs/621248593#L4250
