There does seem to be something wrong with your linux/futex.h, which is much
shorter than the one on my system.  But it is also true that the file where the
error occurs no longer needs to #include <linux/futex.h>.  You should just
remove the #include and carry on.  I'll commit a more comprehensive fix to
mainline.
