Libtsan intercepts the pthread exported functions with 

dlsym(RTLD_NEXT, func_name).  This fails for pthread_join() as it
is present both as a stub in libc and as real operation in libpthread
and the search order is "libtsan.so libc.so libpthread.so".

Force the order "libtsan.so libpthread.so libc.so" so symbols
get intercepted from libpthread first.

Ok: Matthew Green <mrg@netbsd.org>
