It may be that llvm 3.5 + mesa is "using" gcc/binutils in a slightly different
way.
Can you try using the same versions as the one I've listed ? This way if it
works one can start looking for the combination that exhibits the problem.

If the function prototype has changed then a compiler warning is due. Afaict
your issue is at a later stage - link time.

I would recommend disabling LTO until one is able to clearly establish the root
cause. After it's sorted you can get it back on for llvm.

I would recommend that you try the patch, before doing anything.
