I'd assume the one in testsuite.

That's pretty problematic now that we're erroring on unsupported -m
options where we weren't before and changing all of the code in the
world to get rid of their unfortunate use of compiler options is a bit
extra for work. Basically I think this patch is only going back to the
previous behavior and should be fine. Now, I agree that deciding
whether or not we want to implement this and how we should is
important, but I don't know that this is worth holding up things for
since in the freestanding world you'll have an unresolved symbol at
link time and otherwise we error out on code that we would
successfully compile in the past?
