s390: Use dl-symbol-redir-ifunc.h on cpu-tunables
Using the memcmp symbol directly allows the compile to inline the memcmp calls (especially because _dl_tunable_set_hwcaps uses constants values), generating better code. Checked with tst-tunables on s390x-linux-gnu (qemu system). Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
