The integration tests use both libcretonne and libreader, so moving them avoids the circular dev-dependency. Also go back to building everything under src/tools/target to avoid rebuilding the libraries when cargo is invoked in different subdirectories. This speeds up test-all.sh quite a bit. Finally, skip the pure debug build. We build "cargo test" and "cargo build --release" which should cover everything we need.
