## Message

```
breaking changes to the way targets work in zig

 * CLI: `-target [name]` instead of `--target-*` args.
   This matches clang's API.
 * `builtin.Environ` renamed to `builtin.Abi`
   - likewise `builtin.environ` renamed to `builtin.abi`
 * stop hiding the concept of sub-arch. closes #1526
 * `zig targets` only shows available targets. closes #438
 * include all targets in readme, even those that don't
   print with `zig targets` but note they are Tier 4
 * refactor target.cpp and make the naming conventions
   more consistent
 * introduce the concept of a "default C ABI" for a given
   OS/Arch combo. As a rule of thumb, if the system compiler
   is clang or gcc then the default C ABI is the gnu ABI.

```
