Creating 10.0.12 Desktop incrementals fails

We only built 10.0.11 for win32/64. I wonder how we should work around this.

$ make incrementals-release
git submodule update --init
./rbm/rbm build release --step update_responses_config --target release --target create_unsigned_incrementals
tools/update-responses/download_missing_versions release
