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.

I found an issue too. It crashes on the "ar" invocation used to build the armv7 compiler-rt library for cc_kext with the error:

/usr/bin/ranlib: object: /Users/jddupas/Projects/llvm/simplebuild/tools/clang/runtime/compiler-rt/clang_darwin/cc_kext/armv7/libcompiler_rt.a(absvdi2.o) malformed object (unknown load command 1)
ar: internal ranlib command failed
