i586: Fix multiple definitions of __memcpy_chk and __mempcpy_chk
/home/bmg/install/compilers/x86_64-linux-gnu/lib/gcc/x86_64-glibc-linux-gnu/13.2.1/../../../../x86_64-glibc-linux-gnu/bin/ld: /home/bmg/build/glibcs/i586-linux-gnu/glibc/libc.a(memcpy_chk.o): in function `__memcpy_chk':
/home/bmg/src/glibc/debug/../sysdeps/i386/memcpy_chk.S:29: multiple definition of `__memcpy_chk';/home/bmg/build/glibcs/i586-linux-gnu/glibc/libc.a(memcpy.o):/home/bmg/src/glibc/string/../sysdeps/i386/i586/memcpy.S:31: first defined here /home/bmg/install/compilers/x86_64-linux-gnu/lib/gcc/x86_64-glibc-linux-gnu/13.2.1/../../../../x86_64-glibc-linux-gnu/bin/ld: /home/bmg/build/glibcs/i586-linux-gnu/glibc/libc.a(mempcpy_chk.o): in function `__mempcpy_chk': /home/bmg/src/glibc/debug/../sysdeps/i386/mempcpy_chk.S:28: multiple definition of `__mempcpy_chk'; /home/bmg/build/glibcs/i586-linux-gnu/glibc/libc.a(mempcpy.o):/home/bmg/src/glibc/string/../sysdeps/i386/i586/memcpy.S:31: first defined here

After this change, the static library built for i586, regardless of PIC
options, contains implementations of these functions respectively from
sysdeps/i386/memcpy_chk.S and sysdeps/i386/mempcpy_chk.S.  This ensures
that memcpy and mempcpy won't pull in __chk_fail and the routines it
calls.
