What pkgsrc actually does is "every program in pkgsrc that can possibly
use dlopen() (either directly or indirectly) is linked with pthreads *on
NetBSD>=2.0 and NetBSD<=2.99.10*. I believe that NetBSD's native
libpthread and libc were modified in subsequent versions to not require
Admittedly, this test is sub-par since we check for a specific NetBSD
version instead of using a feature-test, so this check breaks for users
whose kernel and userland are not in sync. However, I couldn't come
with with a reasonable test that didn't require invoking a compiler and
linking a test program. If anyone knows of a test where I could inspect
a header or look for a library symbol using nm(1), please let me know.
