Option to suppress xilink output messages?

I'm using SCons to build a project with ICC on Windows, and I get a lot of xilink messages in the console that look like this:

xilink: executing 'link'
   Creating library path\to\file\file.lib and object path\to\file\file.exp

I believe these messages are output to stderr and are really polluting my console. I found no ICC option to suppress them. What's the proper way to do this, apart from the brute-force and sub-optimal forwarding of stderr output to NUL?

Thanks!
