printf warning in gnumach

[Pietro Braione]

Hello; my first (extremely small) contribution, just to understand how to 
report bugs and propose patches. I am addressing build warnings in gnumach, and 
this patch fixes a printf format warning in the sundance Linux driver. Let me 
know if the submission format is correct.
