[Daniel Dunbar]

It looks to me like cctools ranlib just can't understand the ARM
object files. I took Bob's tack in:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=166114
and just drop them on 10.6.

I tested this on a 10.6 machine and it resolves the issue for me, let
me know if it doesn't work for you for some reason.

Cheers,
 - Daniel

In your case, it is going ahead and building armv7 for both cc_kext and cc_kext_ios5 but failing intermittently, apparently when creating the archive.
