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.

If you apply the attached patch to clang, and build using "make VERBOSE=1" it should print all compilation commands (including runtime libraries compilation).

Maybe it can help to nail down the source of the problem.

I have a 10.6 machine and will try to reproduce the bug too.
