Yes.

Apparently -fno-stack-protector doesn't actually work the way
I/we would expect.

But, I'm surprised that this doesn't affect the building
of NetBSD's own 'stand' code.

FWIW, the pkgsrc-wip package just patches in a dummy
function.  patch-ag and patch-ah.

Aside from those patches it built pretty much
out-of-the-checkout for me.
