The symbol was moved using scripts/move-symbol-to-libc.py. A small adjust to the sem_unlink implementation is necessary to avoid a check-localplt failure. A placeholder symbol to keep the GLIBC_2.1.1 version alive in libpthread is added with this commit. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
