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.
