Hi Heinrich,

While both unified and separate images can not be generated at the same
time, a build flag can be used by which the user can build one of
the schemes matching qemu capabilities. Default will be separate
code and vars matching the latest qemu.

I believe this will alleviate the concern. If this looks better, let me
test and send v2.

Thanks!
Sunil
