again, don't make more out of this than what i'm proposing.  in order
to short-circuit some of the discussion, i've attached my old mini-ct
script which, as you can see, is fairly simplistic but has built
perfectly functional toolchains for some architectures.  (it's been a
while since i've looked at it myself, so i'm having to refresh my
memory as to why i did certain things.  :-)

once again, i'm not trying to address the corner cases, and i know
there's lots of them.  i'm trying to distill what's *essential* in the
simple cases, so there's still a couple questions i've asked for which
no one has suggested an answer:

1) is there any *theoretical* reason why the generated headers from
the latest kernel source tree shouldn't work for *all* builds?  yes or
no?  if not, why not?

2) is my recipe for configuring and building binutils acceptable?  yes
or no?

let's start with the simple stuff first and see where this goes, ok?

p.s.  as i've already mentioned, one of the main reasons i wrote
mini-ct in the first place was just to clarify in my own mind what the
heck was going on in the build process.
