I was meaning to ask what changed you'd have to make to get your image
to build.

By strange coincidence I was looking at gcc-cross-initial today and
wondered about this. I concluded that gcc-cross-initial does not need
sysroot support though. gcc-cross-initial is only used to build the libc
for gcc-cross "proper" and for that you don't need anything in staging.

So the question is why would gcc-cross-initial need to find things in
staging?
