S390: Add z13 strstr ifunc variant.
The new vector variant of strstr is using the common code implementation, but instead of calling the default str* / mem* functions, the vector variants are called. ChangeLog: * sysdeps/s390/Makefile (sysdep_routines): Add strstr variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variants for strstr. * sysdeps/s390/ifunc-strstr.h: New file. * sysdeps/s390/strstr.c: Likewise. * sysdeps/s390/strstr-c.c: Likewise. * sysdeps/s390/strstr-vx.c: Likewise.
