configure: Allow disabling pthreads, fall back on Win32 threads
When the threaded resolver option is specified for configure the default
thread library is pthreads. This change makes it possible to
--disable-pthreads and then configure can fall back on Win32 threads for
native Windows builds.
Closes https://github.com/curl/curl/pull/1260
