[tlbuild] Tex Live 2013 pretest binaries for NetBSD/i386 and NetBSD/amd64 6.0.1

[Karl Berry]

Hi Marc,

    As to adding back NetBSD binaries to TeX Live, why not? I'll
    gladly provide them if you think they're OK.

Well, I have no way of knowing or testing anything about them.  Since
they (presumably :) work for you, that's good enough for me.  I'll
install them into TL as soon as I have a chance.

Thanks!

Karl
