The warnings are harmless, but regardless libLTO shouldn't be trying to 
build on any platform except Darwin.

It looks like the 2.5 rebranching took place at just the wrong time and 
picked up a change when I tried to have libLTO build on Linux as well. 
That change should never have made it into the 2.5 branch.

Tanya, could you please revert 62987 from the 2.5 branch? It's this patch:
http://llvm.org/viewvc/llvm-project/llvm/branches/release_25/tools/Makefile?r1=62895&r2=62987

fortunately just a one-liner. I'm really sorry for the trouble...
