std: Add a helper for symbols that may not exist
Right now we only attempt to call one symbol which my not exist everywhere, __pthread_get_minstack, but this pattern will come up more often as we start to bind newer functionality of systems like Linux. Take a similar strategy as the Windows implementation where we use `dlopen` to lookup whether a symbol exists or not.
