The issue is due to commit c3005475889c "ARC: build: retire old toggles" which
removed supposedly obsolete toggles just to make way for removing them from the
tools. However it seems they are no so obsolete as I thought they were.

I'm going to have that reverted for now and maybe do this next year when tools are
immune to this change.

@Alexey, I tried 2016.03 and that seems to build fine with that patch - what
version of gcc is Luis using in this buildroot ?
