Huh. Ok, looking deeper, this seems to be due to cgo... the normal
workaround is to 'go build -buildmode=pie', which, sadly, does not
appear supported on netbsd-amd64. This is bigger than just "report
upstream" :/

/usr/pkg/go119/bin/go build -buildmode=pie -tags "" -o bin/bsondump bsondump/main/bsondump.go
-buildmode=pie not supported on netbsd/amd64

So, without pie, ld.elf_so tries to process text relocations, and fails
due to PaX?
