Use libc_hidden_* for argz_next, __argz_next (bug 15105).
Among other localplt test failures when building with -Os, there are libc.so PLT references for argz_next and __argz_next. This is a simple case of functions that are inlined for -O2 but not for -Os; this patch adds libc_hidden_proto / libc_hidden_def for them to avoid localplt failures even when not inlined. Tested for x86_64 (both that it removes these particular localplt failures for -Os - but other such failures remain so the bug can't yet be closed - and that the testsuite continues to pass without -Os). [BZ #15105] * include/argz.h (argz_next): Use libc_hidden_proto. (__argz_next): Likewise. * string-argz-next.c (__argz_next): Use libc_hidden_def. (argz_next): Use libc_hidden_weak.
