I'm afraid this fails 'make check' on at least one config and
generates a lot of ugly warnings on several.

(1) Ugly warning (seems to happen everywhere):

TEST: tests/virtio-blk-test... (pid=28666)
  /arm/virtio/blk/mmio/basic:
WARNING: Image format was not specified for '/tmp/qtest.q0ywpl' and
probing guessed raw.
         Automatically detecting the format is dangerous for raw
images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.
OK

(2) Apparent errors on OSX when trying to use "/dev/null" as an
image file. Weirdly these don't actually cause "make check" to fail,
which suggests something's not propagating an error correctly.

(3) Actual failure, x86_64 host:

TEST: tests/virtio-blk-test... (pid=16564)
  /arm/virtio/blk/mmio/basic:
WARNING: Image format was not specified for '/tmp/qtest.4s4Naf' and
probing guessed raw.
         Automatically detecting the format is dangerous for raw
images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.

This might be an intermittent failure; I think my x86-64 gcc
build passed the first time and failed on a rerun. The clang
build also failed this.
