Could you add the log of the failure?

My guess is that it failed regarding llvm tablegen. We are cross-compiling clspv for ChromeOS, here is how we do it:

First, what you need to do is to build tablegen with your local compiler (no cross compilation).
Have a look at what is done in build_host_tools here.

And then, you just need to keep what you have added plus what is here

If the failure is not related to llvm tablegen forget about everything above obviously.
