$ make -j4 && make install
error: failed to read `/home/cesarb/opt/rust-git/src/rust/src/tools/cargo/Cargo.toml`

Caused by:
  No such file or directory (os error 2)

$ git rev-parse --short HEAD

$ ls src/tools/cargo

The src/tools/cargo directory is empty. Cleaning the checkout (with git clean -f -x -d) and running configure again didn't fix it.

Configure command line: ./configure --prefix=/home/cesarb/opt/rust-git --android-cross-path=/home/cesarb/android-sdks/temp/arm-linux-androideabi --target=x86_64-unknown-linux-gnu,i686-unknown-linux-gnu,x86_64-pc-windows-gnu,arm-linux-androideabi,armv7-linux-androideabi

Can be fixed by

git submodule update --init
