omit qemu from OE build?

[Shawn Rutledge]

After the compiler "badness" on my one gentoo system (which I have no
idea how to resolve) I decided to try on another machine which happens
to be 64-bit and with gcc 4.1, so there isn't much hope of getting
qemu to run.  But openmoko-devel-image or openmoko-image depend on it.
 Is there a way to remove this dependency so I can just build images
for the phone?
