On my laptop, pthread_create() is always available without -lpthread, but when I use -fsanitize=address, -lpthread is required to pull in other threading functions such as pthread_rwlock_tryrdlock(). Thus, with -fsanitize=address I have to manually add -lpthread to link commands one way or another. This commit avoids that problem by checking for a function that is sometimes only available in -lpthread.
