not necessarily, in my branch it is perfectly legal to start qemu without an 
image, as long as the gdb server is started, since the application will be 
loaded by the gdb client. (this is how the Eclipse plug-in is configured to 
start qemu).

for consistency I would suggest to return -1 for all cases that do not return a 
legal cmdline.
