Seems there is an oscillating behaviour of the results as a function of 
binutils version
number: see
http://lists.linuxfromscratch.org/pipermail/lfs-dev/2013-April/067945.html

Actually, "/tools/x86_64-unknown-linux-gnu/lib64" does not exist anyway...

But maybe somebody should change the book again!

BTW, here is the output on i686 (recent build with gcc-4.9.2 and binutils-2.25):
SEARCH_DIR("=/tools/i686-pc-linux-gnu/lib32")
SEARCH_DIR("/usr/lib")
SEARCH_DIR("/lib")
SEARCH_DIR("=/tools/i686-pc-linux-gnu/lib");
