Finished First Pass

Thanks everyone for their answers as to why there are two passes. This is the paragraph I read that confused me about 32 and 64 bit machines, but it looks like I will be able to proceed according to Bruce's answer:

This version of the book builds a 32-bit Linux system and requires an existing 32-bit version of of the
kernel on the Intel/AMD x86 architecture. Adding capabilty for x86_64 systems is a major objective
of a future version of LFS. Support for 64-bit systems and additional architectures can be found in the
Cross-Compiled Linux From Scratch (CLFS) project at

"Chapter 5  packages are built using this second pass toolchain. When 
this is done, the LFS installation process will no longer depend on the 
host distribution, with the exception of the running kernel."

"the instructions in this book are known to work, with some 
modifications, with both Power PC and 64-bit AMD/Intel CPUs. To build a 
system that utilizes one of these CPUs, the main prerequisite, in 
addition to those on the next few pages, is an existing Linux system 
such as an earlier LFS installation, Ubuntu, Red Hat/Fedora, SuSE, or 
other distribution that targets the architecture that you have."
