If you take a look at malloc and linuxthreads, you will find that both
libc and linuxthreads define them and we are expecting "-lpthread"
will replace the ones in libc with the ones in linuxthreads. From
linuxthreads/Versions:

    # Internal libc interface to libpthread
    __libc_internal_tsd_get; __libc_internal_tsd_set;

what it means libc has to export them so that libpthread can override
them. I hope it is clear now.
