In our previous FORTIFY_SOURCE change, we started using a custom inline for memcpy(), rather than using GCC's __builtin_memcpy_chk(). This allowed us to delete our copy of __memcpy_chk(), and replace it by __memcpy_chk2(). Apparently GCC uses __memcpy_chk() outside of __builtin_memcpy_chk(). Specifically, __memcpy_chk() is used by __builtin__memMOVE_chk() under certain optimization levels. Keep the old __memcpy_chk() function around, and have it call into __memcpy_chk2().
