    Look at coregrind/m_redir.c:1364

    /* If we're using memcheck, use these intercepts right from the
       start, otherwise ld.so makes a lot of noise.  In most ARM-linux
       distros, ld.so's soname is ld-linux.so.3, but Ubuntu 14.04 on
       Odroid uses ld-linux-armhf.so.3 for some reason. */

    ...

       /* strcmp */
       add_hardwired_spec(
          "ld-linux.so.3", "strcmp",
          (Addr)&VG_(arm_linux_REDIR_FOR_strcmp),
          complain_about_stripped_glibc_ldso
       );


   I think, on some machines running linux strcmp() function resides in 
ld-linux.so. But look on same for x86: just NULL passed to 
add_hardwired_spec() function. I think, you need to do the same.
