Make sure you have the line

sed -e 's@/lib\(64\)\?\(32\)\?/ld@/tools&@g'

right. If you have just the slightest typo, the files are not modified
(and there is no warning...).
Now that you mention it Pierre, I think the following would be better
because it is far easier to read and understand.
sed -e 's@/lib../ld@/tools&@g'
where the '.' matches any character.
Actually the only files that match are
gcc/config/rs6000/linux64.h
gcc/config/i386/linux64.h
gcc/config/tilegx/linux.h
gcc/config/mips/linux.h
For this construct, only the 2nd file above affects us.
For the 2nd expression, I can't find any file that would affect us (only
sparc and rs6000).
Hmm,
Not completely sure, but I think we need to be able to match /lib/ld (for
32 bit), which is not matched by /lib../ld.
We could use -r 's@/lib(..)?/ld@/tools&@g' to cover /lib/ld.
I prefer not using what 'man 7 regex' calls Obsolete ("basic") regular
expressions. Otherwise there are too many backslashes that interfere with
understanding what is going on. The equivalent in grep is using the -E
option or egrep.
Actually, the regexp in the book is matched by many files
gcc/config/sparc/linux64.h
gcc/config/sparc/linux.h
gcc/config/rs6000/linux64.h
gcc/config/rs6000/sysv4.h
gcc/config/mn10300/linux.h
gcc/config/vax/linux.h
gcc/config/bfin/linux.h
gcc/config/s390/linux.h
gcc/config/mips/linux.h
gcc/config/xtensa/linux.h
gcc/config/i386/linux64.h
gcc/config/i386/linux.h
gcc/config/cris/linux.h
gcc/config/nios2/linux.h
gcc/config/m68k/linux.h
gcc/config/frv/linux.h
gcc/config/microblaze/linux.h
gcc/config/ia64/linux.h
gcc/config/tilepro/linux.h
gcc/config/m32r/linux.h
gcc/config/linux.h
gcc/config/tilegx/linux.h
gcc/config/sh/linux.h
We should be hesitant in changing instructions that have worked for so
long, but the only files that should affect us are those that begin with
gcc/config/i386/
The only files that have lib32 are:
gcc/config/mips/linux.h
gcc/config/tilegx/linux.h.
The ones that match lib64 are:
gcc/config/mips/linux.h
gcc/config/sparc/linux64.h
gcc/config/i386/linux64.h (one place)
gcc/config/rs6000/linux64.h
The find for sysv4.h should be irrelevant for us.
