+`--disable-cpu-optimizations'
+
+ By default the configure script will attempt to detect the type of your
+CPU and enable any features specific to your CPU that could optimize the
+performance of the Toolkit. If you are creating binary package that should
+work on any CPU (and not only your CPU) you should diable these
+optimizations. If you compile it for yourself only, keeping the
+optimizations enabled is recommended.
