Pardon?

Are you asking if osstest builds stubdoms? I think so and
http://www.chiark.greenend.org.uk/~xensrcts/logs/29421/build-amd64/5.ts-xen-build.log
 seems to contain evidence of it happening.

I think there is a certain amount of dependence on the gcc version in
this stuff. osstest uses gcc 4.7.2 from Debian 7.0 (Wheezy, current
stable)
