cargo clippy fails with "error: multiple input filenames provided"

[imp]

cargo clippy started to fail on my crates this morning, after routine rustup update
Apparently, the problem is reproduced on a fresh crate as well:

$ cargo new --lib xxx
     Created library `xxx` project
$ cd xxx/
$ cargo clippy
lib: xxx
   Compiling xxx v0.1.0 (file:///Volumes/rust/xxx)
error: multiple input filenames provided

error: Could not compile `xxx`.

To learn more, run the command again with --verbose.
$ cargo -V
cargo 1.26.0-nightly (d10ec661b 2018-03-20)
$ rustc -V
rustc 1.26.0-nightly (f5631d9ac 2018-03-24)
$ cargo clippy -V
0.0.189

Maybe the flipside of rust-lang/cargo#5208? Workaround seems to be running cargo-clippy directly.

Hi, looks like a duplicate of #2566
