I'd encourage you to loook at installing as many deps as possible to
maximise the coverage. eg gnutls, nettle, spice, and anything else that
is relevant

Are the Cirrus CI environments SMP ? If so adding a -j flag would
give much improved build times.

The trouble is that these are all VMs, and (AFAIK) none of the free CI
services let you spin up arbitrary VM images with KVM, only allow for
custom docker images.

So unless there's some way for us actually run the VM images on a public
CI that we already use, I think it is reasonable to use Cirrus CI for
FeeBSD testing.
