How to do 32-bit build in AMD64 chroot -- problem with SSE instructions?

[Steven Robbins]

Hi,

I've built the ITK package on my AMD64 machine without trouble, but the 32-bit 
build is failing with the error below. 

The errors seem to point to using SSE instructions.  Is there a recommended 
set of flags to use when building for x86?  I tried "-march=i686" but it gives 
the same error.

Below is the first warning and error -- there are several more similar errors.

Thanks!
