I had tried different combinations of flags and still got errors, the
gcc side looked fine to me.

What version of binutils is in pkgsrc ?

I was hoping that the binutils update that is in progress might help
with this, we would still need to do something for NetBSD-9 though.

I also have a patch that I was about to commit that adds detection of
support for these instructions on NetBSD. Without the patch, nss
wouldn't call the code that is failing to build.
