tools build feature: Check if pthread_barrier_t is available

Browse Source 
commit 25ab5abf5b141d7fd13eed506c7458aa04749c29 upstream.

As 'perf bench futex wake-parallel" will use this, which is not
available in older systems such as versions of the android NDK used in
my container build tests (r12b and r15c at the moment).
