The same basic problem you're having here was reported on IRC last week during the LLVM dev meeting. I've started a thread on llvm-dev to discuss this problem and possible solutions. I'm not completely opposed to this as a temporary solution, but it actually won't work for most cases.

In the normal CMake cross-compiling process you won't get anywhere near this far through configuring the build because all of the `try_compile` and `check_cxx_compiler_flag` calls will fail. I assume the only reason that isn't biting you is because you're not actually cross-compiling via a CMake toolchain, you're relying on the hacked-in cross compiling capabilities in Compiler-RT's build.

I do not want to block you from making progress, but I think it would be best for the project if we can at least discuss the long-term solution to this problem before we talk about temporary workarounds.

I would encourage you to participate in the discussion, the thread is: http://lists.llvm.org/pipermail/llvm-dev/2015-November/091916.html

Thanks,
-Chris
