Thank you for your report.

What pkgsrc are you using? (current, release (which one)).
And If you update the system to 9.99.92, does it still fail?

From what I have read, RELRO is relatively new (initial support dates a
few years ago), but it seems that it has already cause a few issues
here and there already [1]. I would suspect that it has been fixed in
newer versions of pkgsrc (current) and NetBSD.

Do you have any modified option in your mk.conf [2]?
