portage 2.1 introduced the new EMERGE_DEFAULT_OPTS feature. Unfortunately this feature causes a problem with module-rebuild, particularly when --ask is used as a default option. The "ask" section of the output isn't displayed making it appear that module-rebuild has stalled (you can hit 'y' then enter and it will proceed as expect). This patch adds the new --ignore-default-opts flag to the call to emerge.
