Yes, livepatch-build-tools will fetch the alt_intsrt size from the
DWARF info.

However when using create-diff-object without the env variable being
set a default value is used, and that's currently 12.  I think it
would be best to update that default to the value used by the current
Xen version.

Thanks, Roger.
