Testing for 32-bit x86 shows up a warning "tst-nss-test1.c:25:3: warning: format '%ju' expects argument of type 'uintmax_t', but argument 2 has type 'int' [-Wformat=]". The argument is a difference of two pointers, a signed quantity of type ptrdiff_t for which the right format is %td; this patch makes this test use that format. Tested for 32-bit x86. * nss/tst-nss-test1.c (do_test): Use %td printf format for pointer difference, not %ju.
