The ifunc handling for wcscat is adjusted in order to omit ifunc if the minimum architecture level already supports newer CPUs by default. Unfortunately the c ifunc variant can't be omitted at all as it is used by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned. ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove wcscat variants. * sysdeps/s390/Makefile (sysdep_routines): Add wcscat variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for wcscat. * sysdeps/s390/multiarch/wcscat-c.c: Move to ... * sysdeps/s390/wcscat-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcscat-vx.S: Move to ... * sysdeps/s390/wcscat-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcscat.c: Move to ... * sysdeps/s390/wcscat.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-wcscat.h: New file.
