Constant user functions are supported in the development branch of iverilog, 
so you will need to build and install a development snapshot to solve this. 
Instructions on how to do this can be found here:

Last time I used them (which was a few years ago), the Xilinx tools worked 
well from the Linux command line. All my FPGA builds were done via Linux shell 
scripts. The GUI could be used in Linux too, although I never bothered with it.

I am not aware of any third-party tools that can generate bitstreams for 
Xilinx devices.
