13:17 < jakub> richi: libgomp defines FUTEX_{WAIT,WAKE} on its own rather then 
               including linux/futex.h, guess the googlers could consider such 
               a change on libasan side too

is one way of avoiding to include a kernel header (the failing header is
from 2.6.18, __user is not properly cleaned from it).
