The linux-ppc64 buildlets run on PPC64 VMs at osuosl.org (OSU Open Source Lab).

They run Debian jessie.

* go-be-xenial-3: (10 GB RAM, 50 GB disk, 10 cores, POWER8)

  ssh -i ~/.ssh/id_ed25519_golang1 ubuntu@140.211.169.164

* Old machines, to be returned: (currently Debian jessie)

  go-be-1: debian@140.211.168.40
  go-be-2: debian@140.211.168.41
  go-be-3: debian@140.211.168.42
  go-be-4: debian@140.211.168.43
  go-be-5: debian@140.211.168.44

Each was once configured by scping setup.bash to them, logging in to
each, and running:

$ sudo ./setup.bash <BUILDKEY_HERE>

TODO: these should be updated like linux-arm and linux-arm64 to use Docker
      per build. That is https://golang.org/issue/21189
