    Fix elf/tst-unique4lib.cc warning.

    This patch fixes a warning "tst-unique4lib.cc:17:12: warning: 'b'

    defined but not used [-Wunused-variable]".  I'm not sure exactly what

    aspects of the test are or are not significant for the issue it is

    testing for; the patch makes the minimal change of marking the

    variable with __attribute__ ((used)).

    Tested for x86_64.

            * elf/tst-unique4lib.cc (b): Mark with __attribute__ ((used)).
