Sadly, I tried all of the suggestions again, and none of them work. I am not alone. Google searches show that many people have encountered this problem. I believe that there need to be changes within the gcc source trees to automatically detect the lack of /usr/include and to then go to plan B, using xcrun to determine where /usr/include is really located, in order for a full bootstrap build to work.
