clippy fails on missing eh_personality although panic-strategy is defined in custom target

[andre-richter]

When working with no_std crates that have a custom target, it is possible to to define "panic-strategy": "abort" in the custom target .json file, and xargo will happily compile your crate without a definition of the eh_personality lang item.

However, clippy will fail:

xargo clippy 
[...]
error: language item required, but not found: `eh_personality`

error: aborting due to previous error

One workaround is:

RUSTFLAGS="-C panic=abort" xargo clippy
Compiling core v0.0.0 ...

but that causes recompilation of core.
Another one would be adding the item to your source, although it is not needed.

I'm not really sure which of all the involved tools is the culprit here, I'm happy to raise the bug elsewhere if needed.

This is a tad late, but maybe it will help someone who finds this via search. In order for xargo clippy to work with a custom target, you either do xargo clippy --target=your_target or set a default target in .cargo/config and invoke xargo clippy. Either that or I can't reproduce this bug ¯_(ツ)_/¯

That actually makes sense, hehe.

Closing this since solution is now posted.
