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)).
