-pthread like -openmp should always be the right option to use. gcc/g++ and other are compiler drivers (the real compilers are cc1/cc1++) and those switches tells the driver to set everything right for compiling and linking with these features.
That’s the theory at least. Do you have an example where -pthread at linking time doesn’t do its job? The -lpthread could be just someone not understanding the feature, after all, there is a libpthread.
