description:
Skip most of the mixerctl tests when running under QEMU (assumed to be for ATF)
as the kernel that runs them has no audio (and no mixers) configured.

The usage message test might be returned some day if /usr/bin/mixerctl
gets modified so it doesn't attempt to open the device (and error out)
in cases where the device isn't actually going to be used (and -d wasn't
given to set the device name explicitly).
