Just to be sure, when using ldd you should see a difference when setting 
the LD_ASSUME_KERNEL variable.
Specifically, the libraries with NPTL are located in /lib/tls while the 
others are located in /lib.

pissaris at C080:~$ ldd /usr/bin/valgrind-listener
                libc.so.6 => /lib/tls/libc.so.6 (0x40040000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
pissaris at C080:~$ LD_ASSUME_KERNEL=2.4.18 ldd /usr/bin/valgrind-listener
                libc.so.6 => /lib/libc.so.6 (0x40040000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

With friendly regards,
Takis
