Mm, true.

I can think of two things which might turn out to be show-stoppers:
First, the desire to use /proc/self/exe.  I suspect that feature came
to NetBSD with netbsd-8.  If I recall correctly there was a workaround
made for this, but I suspect it also needs newer code than what's in
netbsd-7.  I'm a bit vague on this, as i don't off-hand remember the
exact details.  The second could very well be that the gcc in netbsd-7
is quite old, and perhaps too old to build rust.  However, truth be
told, I have not actually attempted such a build, so "who knows".
