Add a guideline for target-specific behavior. #58

Closed ehuss closed 6 months ago

ehuss commented 6 months ago

This adds a vague guideline about target-specific behavior.

There is a potential intertwined relationship with implementation-specific (#29) and version-specific rules, and other intentionally unspecified behaviors (#28). I expect to follow up with those later.

Closes https://github.com/rust-lang/spec/issues/44
