There's a table cell called blog_links_blog_ID. Why don't we get a routine to push all values for blog_links_blog_ID into an array, then in _main.php, do:
$link_blog_ids = get_link_blog_ids(); //NEED THIS ROUTINE
locale_temp_switch( $Item->locale ); // Temporarily switch to post locale
if (in_array($Item->blog_ID, $link_blog_ids)){ continue; } // Skip bloglinks when found
Cool huh?
