 The following configurations must be defined by the implementation:
 
-* `target_arch = "..."` - Target CPU architecture, such as `"x86"`,

-  `"aarch64"`. This value is closely related to the first element of

-  `"freebsd"`, `"dragonfly"`, `"bitrig"` , `"openbsd"` or
-  `"netbsd"`. This value is closely related to the second and third
-  element of the platform target triple, though it is not identical.
+* `debug_assertions` - Enabled by default when compiling without optimizations.
+  This can be used to enable extra debugging code in development but not in
+  production.  For example, it controls the behavior of the standard library's
+  `debug_assert!` macro.
+* `target_arch = "..."` - Target CPU architecture, such as `"x86"`, `"x86_64"`
+  `"mips"`, `"powerpc"`, `"powerpc64"`, `"arm"`, or `"aarch64"`.
+* `target_endian = "..."` - Endianness of the target CPU, either `"little"` or
+  `"big"`.
+* `target_env = ".."` - An option provided by the compiler by default
+  describing the runtime environment of the target platform. Some examples of
+  this are `musl` for builds targeting the MUSL libc implementation, `msvc` for
+  Windows builds targeting MSVC, and `gnu` frequently the rest of the time. This
+  option may also be blank on some platforms.
 * `target_family = "..."` - Operating system family of the target, e. g.
   `"unix"` or `"windows"`. The value of this configuration option is defined
   as a configuration itself, like `unix` or `windows`.
-* `unix` - See `target_family`.
-* `windows` - See `target_family`.
-* `target_env = ".."` - Further disambiguates the target platform with
-  information about the ABI/libc. Presently this value is either
-  `"gnu"`, `"msvc"`, `"musl"`, or the empty string. For historical
-  reasons this value has only been defined as non-empty when needed
-  for disambiguation. Thus on many GNU platforms this value will be
-  empty. This value is closely related to the fourth element of the
-  platform target triple, though it is not identical. For example,
-  embedded ABIs such as `gnueabihf` will simply define `target_env` as
-  `"gnu"`.

 * `target_pointer_width = "..."` - Target pointer width in bits. This is set
   to `"32"` for targets with 32-bit pointers, and likewise set to `"64"` for
   64-bit pointers.
 * `target_vendor = "..."` - Vendor of the target, for example `apple`, `pc`, or
   simply `"unknown"`.
 * `test` - Enabled when compiling the test harness (using the `--test` flag).
-* `debug_assertions` - Enabled by default when compiling without optimizations.
