To start this email does not belong on the development list. It should
be on the support list.

Also, I had to say the same thing to another user not long ago. leaving
the -gnu off the end of your target triplet is a significant change.
Autotools uses that suffix to determine which libc is being used.

Could you please provide the output of the following 3 commands.

echo $CLFS
file -L /cross-tools/lib/libstdc++.so.6
ls -l /cross-tools

please note that there is no trailing slash on /cross-tools in the last
command.
