Added the missing -mno-sse3 flag to the amd64 section in the /usr/src/sys/conf/ file

I know this is a duplicate of kern/123518 and kern/124463 but
1) kern/123518 has now been open since 8 May 2008
2) kern/124463 was closed as it was a duplicate of kern/123518, yet the fixed has not been MFCed

Is there any reason why this can not be MFCed for the AMD64 platform

in /usr/src/sys/conf/


.if ${MACHINE_ARCH} == "amd64"
 CFLAGS+=        -mcmodel=kernel -mno-red-zone \
-                -mfpmath=387 -mno-sse -mno-sse2 -mno-mmx -mno-3dnow \
+                -mfpmath=387 -mno-sse -mno-sse2 -mno-sse3 -mno-mmx -mno-3dnow
