Fulvio,
a quick and dirty hack that I already used and that should work as well
for you is the following:

1. discover all the dependencies with
   $ ldd yourexecutablename

2. look around in your target system what version libstdc++ is

3. create a symbolic link to the libstdc++ file existing in your target
 using the name your executable wants


Happy hacking ;-)
