This is similar to what I was seeing on some early qemuppc builds as well. fixincludes was tossing out the original file and putting in a broken variant. I had to hide the "fixed" files to build. But then it stopped happening, so I moved on. I'm not familiar with how/when fixincludes fires, so I have no idea about any possible races, etc, that could be happening. I'll do some more research down that route to see if anything pops up.
