Is it possible to specify `panic = “abort”` for a specific target?

问题

If I specify panic like this, it works for all targets:

[profile.release]
panic = "abort"

I want to specify panic = "abort" only for target=arm-linux-androideabi.

You will need to add a .cargo/config to your project and use it to specify the panic settings instead of Cargo.toml:

[target.arm-linux-androideabi]
rustflags = ["-C", "panic=abort"]

The two main configuration headings you will want to look at are [target.$triple] and [target.'cfg(...)'].
