You get most of this behavior for free if you put your configure script directly under 'src', cd to 'obj', and then execute the configure script like /usr/src/configure. You may find it difficult to convince Automake to build from src/lib/lib1 to obj/lib1 since it assumes a mirrored directory tree.
