Don't I get these "unable to infer mode of operation" failures when I don't 
rebuild libtool-base with the new compiler settings?

Btw it took more than three hours to build gcc6, half an hour to build cmake, 
then four hours to build llvm and finally two to three hours (I can't tell 
exactly because it waited for the root PW to install llvm) to build clang. 
All in all it took nearly eleven or twelve hours. Wow.
