Among other localplt test failures when building with -Os, there are libc.so PLT references for __cmsg_nxthdr. This is a simple case of a function that is inlined for -O2 but not for -Os; this patch adds libc_hidden_proto / libc_hidden_def for it to avoid a localplt failure even when it is not inlined. Tested for x86_64 (both that it removes this particular localplt failure 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/sys/socket.h [!_ISOMAC] (__cmsg_nxthdr): Use libc_hidden_proto. * sysdeps/unix/sysv/linux/cmsg_nxthdr.c (__cmsg_nxthdr): Use libc_hidden_def.
