The recent commit 65f7767a91
has introduced __wmemcmp and the weak alias wmemcmp.
This patch also introduces those symbols if glibc is build
with CFLAGS="-march=z13" where the ifunc is omitted.
ChangeLog:
* sysdeps/s390/wmemcmp-vx.S: Add strong alias to
__wmemcmp and weak alias to wmemcmp.
The ifunc handling for wmemcmp is adjusted in order to omit ifunc
variants if those will never be used as the minimum architecture level
already supports newer CPUs by default.
ChangeLog:
* sysdeps/s390/multiarch/Makefile
(sysdep_routines): Remove wmemcmp variants.
* sysdeps/s390/Makefile (sysdep_routines): Add wmemcmp variants.
* sysdeps/s390/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Refactor ifunc handling for wmemcmp.

* sysdeps/s390/wmemcmp-c.c: ... here and adjust ifunc handling.
