build glibc error

the patch seems not correct for me.
I am using glibc-2.10.1 and there is not sysdeps/i386/i686/multiarch/strcmp.S

glibc-2.10.1]$ find . -name strcmp.S
./sysdeps/ia64/strcmp.S
./sysdeps/s390/s390-64/strcmp.S
./sysdeps/s390/s390-32/strcmp.S
./sysdeps/x86_64/strcmp.S
./sysdeps/powerpc/powerpc64/strcmp.S
./sysdeps/powerpc/powerpc32/strcmp.S
./sysdeps/i386/i686/strcmp.S
./sysdeps/sparc/sparc32/strcmp.S
./sysdeps/sparc/sparc32/sparcv9/strcmp.S
./sysdeps/sparc/sparc64/strcmp.S

$ uname -a
Linux xxx.com 2.6.9-52bs #2 SMP Fri Jan 26 13:34:38 CST 2007 x86_64
x86_64 x86_64 GNU/Linux

should I need patch ./sysdeps/x86_64/strcmp.S?
