Bug description:
The test_dllist tests in Lib/test/test_ctypes/test_dllist.py are failing on NetBSD. The issue appears to be that the dl_iterate_phdr function on NetBSD does not report the same information about loaded shared libraries as it does on Linux and other platforms.
Specifically, on NetBSD, dl_iterate_phdr only returns the main Python executable and doesn't include any of the shared libraries that are actually loaded.
./python -m test test_ctypes -m test_dllist -vOutput:
