Hey Peter,

I really do need more serial ports. Two, actually. I'm using qemu on
build.wireguard.com for CI. I have normal output come on ttyS0
(ttyAMA0) and then if it's successful, the final step is writing
"success" into ttyS1 (ttyAMA1), so that I can confirm with certainty
that the tests succeeded. In other words, one channel for text output
and one channel for control messages. (And I really really don't want
to use virtio or PCI-based stuff for this.)

So I'm extending the CI on build.wireguard.com now to support ARM and
MIPS, and things are not very smooth in the ARM world.

Jason
