rsync friendly "latest image" pathname

[James Westby]

I'm not sure how many components nor exactly which ones it involves, but I'd very much like if the ultimate location of the latest image at a fixed pathname as to be rsync friendly and as to easily be able to have a script grab the latest image.

The current Linaro download URLs like http://snapshots.linaro.org/10.11-daily/linaro-headless/20100927/0/images/tar/linaro-m-headless-tar-20100927-0.tar.gz include the date + build id twice, so it requires some ugly HTML parsing / screeenscraping to get the latest image and is not pretty to automate.
