Subject: [PATCH] Add a glossary entry for "target"

The term *target* is used throughout the reference, including in the glossary
itself ("target platform"), but it was never defined.

Add an entry that says what a target is, points out the properties the language
defines in terms of it, and repeats the authoring guideline that the reference
does not document which targets exist or the properties of a particular target.

+### Target
+
+A *target* is the platform that the compiler produces code for: the combination of CPU architecture, operating system, and ABI that the compiled program will run on, usually identified by a target triple such as `x86_64-unknown-linux-gnu`.
+
+Several parts of the language are defined in terms of the target rather than in absolute terms, such as the size of `usize`, or the values of the `target_*` [conditional compilation] keys. The reference documents those properties as properties of the target, but it does not document which targets exist, nor the properties of any particular target.

 ### Trait
 
 A trait is a language item that is used for describing the functionalities a type must provide. It allows a type to make certain promises about its behavior.
