Whoops!  I think he wanted one built from scratch,
not one that used parts of an already-built toolchain.
But if he's ok with a not-quite-from-scratch toolchain,
you are of course right, it's a lot easier if you can
steal the headers and libraries from the target.
(I don't do that with crosstool, simply because I
want to really test whether we can build from scratch.)
