openjdk21 failing on netbsd 9 amd64

[Greg Troxel <gdt%lexort.com@localhost>]

It seems to pass in the bulk builds, but on my system it seems like a
lot of build steps are just skipped.

I have a similar problem with openjdk11 and openjdk17, but openjdk8
builds ok.

Do any of 11/17/21 build for other people on NetBSD 9 amd64?
