With Torvald Riegel's patch ported to current master, the test case works for
both pre and post 3.14.3 kernel versions supplied to --enable-kernel=. I've
tested --enable-kernel=3.0 and --enable-kernel=3.15.

This makes sense, as AFAICS all the __ASSUME defines in question[1] have been
removed from the pthread_cond_ code.
