It seems that you've already built glibc and gone through a few other
sections since the files you are showing come from glibc and the
config.log snippet shows that binutils is trying to look in
/tools/lib. If this was the first time you'd come to Ch. 5.6, neither
of these would be true.

So, if you'd like to go back to build glibc in Ch. 5.6 again, it would
be best to just start from the beginning of Ch. 5. I'd suggest
deleting everything in /tools and starting Ch. 5 again.
