Linux From Scratch: make no such file or directory, bad interpreter

Question

Getting “Not found” message when running a 32-bit binary on a 64-bit system

I have finished the chapter 5 of the book. And after I entered the chroot I realized that make is not working even though it is present.

root:/sources/linux-3.5.2# make mrproper
bash: /tools/bin/make: No such file or directory

the path is correct

echo $PATH
/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin

AND

 ls -l /tools/bin/make
    -rwxr-xr-x 1 root root 559139 Nov 13 11:19 /tools/bin/make

I read on LFS FAQ that is probably due to a bad interpreter (link) so I did

readelf -l /tools/bin/make | grep interpreter
      [Requesting program interpreter: /lib64/ld-linux-x86-64.so.2]

so it's wrong they said it should be something like /tools/lib/ld-linux.so.2

Is there a way to precise when building it the right interpreter ?

Thanks
