It is probably still useful for things like finding the compiler and
setting up installation paths. But I am firmly of the belief that the
less you put in your configure script, the better.

One problem we'll have to solve is shared library generation. A trick
I wanted to try at my former job was beating the magic switches out of
the Perl installation. Watch:

$ perl -V:cc -V:cccdlflags -V:lddlflags
lddlflags='-shared -L/usr/local/lib';

That's almost all the information you need. The only other bit is how
you set the soname, and that is a relatively simple autoconf test.
(I don't know why there's a -L switch in there, but it's harmless.)

I happen to be a big fan of nonrecursive make, but the subversion
layout - to the extent I understand it - could work okay with
recursion too. You've not got a hairy mess of cross-directory
dependencies the way gcc does.
