The problem is that it's the assembly stage that needs the extra
macros.s and without that file being transferred somehow, that stage
must be done locally.

The distcc guys have a thought that the macros.s file might be able to
be transferred using pump mode with a change to include_server.py. I
don't think that will work for icecc though.
