There's a bit more to it than that; we'd wind up having to modify
their build harnesses anyway for things like ensuring that we only
have one copy of config.guess/config.sub in the tree, idna has pieces
that are GPLv3, autopoint was not cooperating with me when run in a
subdirectory, etc. etc. etc.

I rather *want* to have each subdirectory be just as it was in the
original, but right now I don't think that's going to work.

I'll look at that.  I *think* the fix is simple - it appears to just
want one more file - but I was a little scared of the merge process
last night.

I definitely think we want to go that way in the long run, but I'd
rather do that as a separate change than this.

The subdirectory configures must be run from make so we can mess with
their arguments.  There is no way to do that from the top-level
configure script.  Also, this lets me configure the monotone
subdirectory *after* all the libraries are built and installed -- then
it doesn't have to know anything about user selection of bundled
versus system libraries.
