Ah, for this link all the archive libraries into the binary you need to create
libfoo_pic.a for each one of them like you have for libc... It is not hard
to do, but we don't do it by default because people don't need it and it
takes more time and space.

You can always get release shared libraries for all the versions of NetBSD.
Sometimes you need to, because (for example) the object format changes.
