i586: Fix multiple definitions of __memcpy_chk and __mempcpy_chk

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.
