Host system requirements

Even an LFS system wouldn't work as a build host - it doesn't have the  
correct kernel in either case. The only workaround I can see is to  
flesh out Chapter 5 to the point where the target system is minimally  
bootable and self-sufficient, and then boot up the target at the  
beginning of Chapter 6 (instead of entering the chroot).
