Clang and libc were not building correctly on older worlds, for example, on 9.1. * To fix clang add an _xb-bootstrap-tools target that mirrors the existing bootstrap-tools target in the full world. * For libc have the compiler use the newly installed includes, and, while here, tell the compiler about the xdev library path as some other libraries will link against the installed libraries.
