These are now done:

"make qemu" will build qemu-neo1973, download the latest official
openmoko images, flash the images into the virtual NAND flash, and run
the emulator.

Other targets are "make download-images", "make flash-qemu-official" and
"make flash-qemu-local" (which will flash your latest locally built
images) which can then be followed by "make run-qemu" or "make
run-qemu-snapshot".

Make sure you have the "lynx" and "netpbm" packages installed first.
