runqueue: Handle deferred task rehashing in multiconfig builds1.50
If the hash of a task changes and that hash is a deferred task (e.g. a multiconfig build), we need to ensure that the hash change propagates through to all the tasks else the build will run multiple copies of the task, sometimes with oddly differing results as the outhashes of native tasks built in differing locations can confuse things.
