During which stage of buildworld is this? If it is during the cross-tools stage, your host environment is busted somehow. This appears to happen to some people on this list, for unknown reasons. My guess is they either run "make delete-old" before running buildworld (which is the wrong order!), or have done an earlier buildworld where they explicitly disabled clang, so the intrinsics headers never get installed. -Dimitry
