Document limits on static and dynamic linking for HPE NonStop platforms.
Documentation is necessary as static and dynamic linking cause SIGSEGV
during atexit() processing on the platform.

If this +is done, there is a high probability of encountering a SIGSEGV condition +relating to `atexit()` processing when a shared library is unloaded and when +the program terminates.
