Chromium fails to build on SSE misdetection.

[Jonathan Chen]

Hi,

I'm trying to build www/chromium, and it's failing with:

> In file included from third_party/skia/src/opts/SkBitmapProcState_opts_SSSE3.cpp:8:0:
> /usr/local/lib/gcc46/gcc/x86_64-portbld-freebsd9.0/4.6.4/include/tmmintrin.h:31:3: error: #error "SSSE3 instruction set not enabled"

However, this is on a Intel with SSE3:

CPU: Intel(R) Core(TM) i5 CPU         750  @ 2.67GHz (2660.06-MHz K8-class CPU)
  Origin = "GenuineIntel"  Id = 0x106e5  Family = 6  Model = 1e  Stepping = 5
  Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
  Features2=0x98e3fd<SSE3,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,SSE4.1,SSE4.2,POPCNT>

What did I miss?
