It was exactly as you said.

And I executed 'make', an error occurred while building libLTO.so.

I noticed that this error is about the issue 
https://github.com/thewilsonator/llvm-target-spirv/issues/1.

As the issue was opened, I thought I cannot solve the program.

But I noticed you merged to master branch the commit you 
mentioned at the last comment of the issue, so tried to build 
again at the master and made it.

It was the right process?

If it was right, should you change the submodule's commit 
attached to comute branch from 74687b to master?
