I have no idea how to grok what you posted.

The segment I posted was to informational as it is missing the trailing '\'

But since you brought it up....

4.2. Creating a Limited Directory Layout in the LFS Filesystem

  Note

The LFS editors have deliberately decided not to use a /usr/lib64 
directory. Several steps are taken to be sure the toolchain will not use 
it. If for any reason this directory appears (either because you made an 
error in following the instructions, or because you installed a binary 
package that created it after finishing LFS), it may break your system. 
You should always be sure this directory does not exist.


But the book does create lib64 directories,  then tells you is will 
break your system.
