Rustflags via .cargo/config and running tests

Hi there,

Is it possible to specify rustflags in the .cargo/config file only for target build and not for tests?
Suppose I have the following in the config file:

[build]
rustflags = ["-C", "link-args=exports.def"]

I need to skip this when running cargo test. Tried with the following but it didn't work:

[target.'cfg(not(test))']
rustflags = ["-C", "link-args=exports.def"]
