The image is located in build/images/ called image.elf.  Building for
IA-32 will also build a bootable hard disk image located in the
same place, you can either use the simulate target or to save time,
I sometimes run it manually with:

qemu -nographic -serial stdio -hda /path/to/c.img

Would it be possible for us to get some idea on what you plan to use it for
and / or requirements?  Also, would it be possible for you to share with 
us how you intend the system to be structured, e.g. as a standalone 
application running directly on top of the L4 kernel, as a standalone OKL4 
application, as a OK Linux application etc so we can advise with the best 
way to proceed.
