ARC support has been removed for GCC 4.7, but it looks like there's an issue
here potentially relevant to other targets.

Actually it was fixed in r0-99280-g43ba743ca91e5d.

Funny the issue was fixed 3 months before this comment was added but I don't
think Steven realized it though.

Just a quick note the patch which was committed is almost exactly what was
submitted even except it uses a common function now. Even the comments are
almost the same; note I doubt the author of the committed patch even knew about
the old patch but they look very similar to each other.

Someone should dust off the patch and submit it for trunk. Joern?
