How can I test whether COMPILER_RT_DEFAULT_TARGET_ARCH was set explicitly? In my case, TARGET_TRIPLE = COMPILER_RT_DEFAULT_TARGET_TRIPLE and thus COMPILER_RT_HAS_EXPLICIT_DEFAULT_TARGET_TRIPLE=False (when I explicitly specify COMPILER_RT_DEFAULT_TARGET_TRIPLE=mips-mti-linux in the cmake command line).

Other than that, I believe that what you suggested should be working for me.

Yes. For the builtins library, we only need the kernel headers and the headers from the C library.
