cargo install cargo-outdated fails with CARGO_INCREMENTAL=1

[jplatte]

I'm not sure where this should be reported, but seen as it only happens with incremental compilation, I thought here might be a good place. Here is the full output of cargo install cargo-outdated --verbose – it's probably just the last lines that matter, but I figured I should post the full thing in case I'm wrong about that:

[alexcrichton]

Thanks for the report! I think Cargo needs to detect lto and just forcibly disable incremental compilation when used.

[adwhit]

I think this is quite a bad bug. If the user is on nightly and has CARGO_INCREMENTAL=1 in their shell config, then AFAICT every cargo install <crate> will fail with a relatively cryptic error message. Even just a hint ("Hint: Try disabling incremental compilation") would be very useful.

[ehuss]

As of the latest nightly, rustc now supports incremental with LTO, so this should not produce an error. See rust-lang/rust#58378
