i686: Fix multiple definitions of __memmove_chk and __memset_chk 
Commit c73c96a4a1 updated memcpy.S and
mempcpy.S, but omitted memmove.S and memset.S.  As a result, the static
library built as PIC, whether with or without multiarch support,
contains two definitions for each of the __memmove_chk and __memset_chk
symbols.

/usr/lib/gcc/i686-pc-linux-gnu/14/../../../../i686-pc-linux-gnu/bin/ld: /usr/lib/gcc/i686-pc-linux-gnu/14/../../../../lib/libc.a(memset-ia32.o): in function `__memset_chk':
/var/tmp/portage/sys-libs/glibc-2.39-r3/work/glibc-2.39/string/../sysdeps/i386/i686/memset.S:32: multiple definition of `__memset_chk'; /usr/lib/gcc/i686-pc-linux-gnu/14/../../../../lib/libc.a(memset_chk.o):/var/tmp/portage/sys-libs/glibc-2.39-r3/work/glibc-2.39/debug/../sysdeps/i386/i686/multiarch/memset_chk.c:24: first defined here

After this change, regardless of PIC options, the static library, built
for i686 with multiarch contains implementations of these functions
respectively from debug/memmove_chk.c and debug/memset_chk.c, and
without multiarch contains implementations of these functions
respectively from sysdeps/i386/memmove_chk.S and
sysdeps/i386/memset_chk.S.  This ensures that memmove and memset won't
pull in __chk_fail and the routines it calls.
