Actually, there are two bugs here: * Build for 4.11 fails, see bug 1713638 (patch included there). * Build for 4.13 fails: I can confirm that, but a different patch is needed. I personally can't run this kernel yet because of that bug.
Lots of similar bugs have been reported, see https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bugs?orderby=-date_last_updated&start=0 (for different kernel versions, including also 4.4 and 4.10).
