How do ld know which library to load for an application?
Many applications using sockets run the socket-code from libc,
but if the application is using pthreads, it will need to use
the socket-calls in libpthread. How does ld know which library to
choose?

It doesn't. It searches for undefined symbols in libraries specified to it,
in the order in which they are specified (searching iteratively if
required).

Specify -lpthread on the command line while linking the executable. Actually
you need to place it before -lc which if not specified explicitly occurs
after the user specified libraries in the search order.
