I have double-checked and tried the compilation over and over again so can anyone think of anything that I'm missing ignoring the possibility of typos?

FYI, if you change /tools to /mnt/clfs/tools, after you boot into the
final system, you would have to actually put tools in
/mnt/clfs/mnt/clfs/tools after you chroot. The reason for the symlinks
is so that /tools keeps the same relative paths inside and outside of
the chroot.

I don't know exactly what your setup is, but you have 2 options really,
attempt to use sysroot to move /tools into your target only. I forget
exactly why the book doesn't have this, there is a reason, I think there
were problems building from OpenSolaris.

The easiest option, during your build, along the same lines, just rename
/tools to something else like /tools-ppc or /tools-x86_64.

I havn't ever done this but you can probably run a sed over the books
and patches before you start this may you're less likely to make
mistakes as you go.
find BOOK/ patches/ -type f -exec sed -i "s,/tools,&-ppc,g" '{}' \;
