It'd make more sense for pg_config to expose this as one of the
available information bits.  The difference from the thread-support
case is that you'd typically want to get the pg_service.conf location
manually, and that's exactly what pg_config is designed for.  Verifying
thread support, on the other hand, is something that a program would
want to do.
