[Pkg-rust-maintainers] 1.7 nightly builds/tests ok but fails "binary" target

[Ximin Luo]

I auto-generated source tarballs out of current git using the attached script. It builds fine but fails during "fakeroot debian/rules binary". I don't have time to debug it right now but I thought perhaps the error would be more easily recognised by someone else.

Packages are here: https://people.debian.org/~infinity0/apt/pool/contrib/r/rustc/
