Trying to get MALTA64 running under qemu

The mkimg step is missing from the instructions on the wiki, as are the
arguments to makefs to get it to include some spare inodes in the image.
I haven't yet found any way to pass boot-time arguments to the kernel
(qemu's -append option doesn't seem to work, or I'm passing the
arguments wrong) so the root fs has to be on ada0s1a.

This comes up successfully with qemu-devel-2.0.2_3. The 'malta' machine
seems to be rather limited (one CPU, no more than 256M memory); I might
see if I can get a kernel config that works with one of the other qemu
machines.
