i386 has the same issue. I am checking in this.

Subject: [PATCH] i386: Test memmove_chk and memset_chk only in libc.so [BZ
#21741]
Since there are no multiarch versions of memmove_chk and memset_chk,
test multiarch versions of memmove_chk and memset_chk only in libc.so.
[BZ #21741]
* sysdeps/i386/i686/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Test memmove_chk and memset_chk only
in libc.so.
