a22797d356 systems: fix netbsd triple parsing
binutils expects x86_64-unknown-netbsd<version> (only 3 parts!). Any other combo seems to fail.

Also handle darwin versions similarly.

6a96dc0417 lib/system: Remove float from androideabi
There are two different official variations which differ in their float
support, so such a blanket statement is invalid.
`lib.systems.platforms.*android` already handles each case correctly.

Correcting an error in 827ef09140.

1fe81a4bcd lib: Clean up float/fpu options
ARM ABIs now have a float field. This is used as a fallback to lessen
our use of `platform.gcc.float`. I didn't know what the MIPs convention
is so I kept using `platform.gcc.float` in that case.

b9acfb4ecf treewide: isArm -> isAarch32
Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.

The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:

```
ISA:             ARMv8   {-A, -R, -M}
                 /    \
Mode:     Aarch32     Aarch64
             |         /   \
Encoding:   A64      A32   T32
```

At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.

The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

bbfa2f9701 lib: Split Darwin into macOS and iOS
I noticed LLVM accepts `ios` as its own OS in platform triples; a
recent change as far as I know. I see it also accepts `macos*` for macOS
(formerly OS X). If it's now customary to distinguish iOS like so
(rather than guessing from the aarch, lets add both so our OSes are
still disjoint, and make Darwin a family instead.

But changing the config everywhere would probably be a mass rebuild, and
I'm not sure how well other software supports OSes besides "darwin", so
I'm keeping that the default name for macOS for now.

9c50ae6898 lib, treewide: Add missing MIPS arches, and fix existing usage
Existing "mips64el" should be "mipsel".

This is just the barest minimum so that nixpkgs can recognize them as
systems - although required for building individual derivations onto
MIPS boards, it is not sufficient if you want to actually build nixos on
those targets

ad78ba1efa lib: Better use the module type system in platform parsing
I need some module system types here so I can next fix meta-checks for
derivations. I'd like to use a "proper" record type here, but submodule
types seem overkill so holding off with ad-hoc stuff for now. In
practice, all I need for the next step are the `.check` functions so
this is good, especially as the submodule check function is shallow,
saving full inductive type-checking for a later step.

Convert libs to a fixed-point
This does break the API of being able to import any lib file and get
its libs, however I'm not sure people did this.

I made this while exploring being able to swap out docFn with a stub
in #2305, to avoid functor performance problems. I don't know if that
is going to move forward (or if it is a problem or not,) but after
doing all this work figured I'd put it up anyway :)

Two notable advantages to this approach:

1. when a lib inherits another lib's functions, it doesn't
   automatically get put in to the scope of lib
2. when a lib implements a new obscure functions, it doesn't
   automatically get put in to the scope of lib

Using the test script (later in this commit) I got the following diff
on the API:

  + diff master fixed-lib
  11764a11765,11766
  > .types.defaultFunctor
  > .types.defaultTypeMerge
  11774a11777,11778
  > .types.isOptionType
  > .types.isType
  11781a11786
  > .types.mkOptionType
  11788a11794
  > .types.setType
  11795a11802
  > .types.types

This means that this commit _adds_ to the API, however I can't find a
way to fix these last remaining discrepancies. At least none are
_removed_.

Test script (run with nix-repl in the PATH):

  #!/bin/sh

  set -eux

  repl() {
      suff=${1:-}
      echo "(import ./lib)$suff" \
          | nix-repl 2>&1
  }

  attrs_to_check() {
      repl "${1:-}" \
          | tr ';'  $'\n' \
          | grep "\.\.\." \
          | cut -d' ' -f2 \
          | sed -e "s/^/${1:-}./" \
          | sort
  }

  summ() {
      repl "${1:-}" \
          | tr ' ' $'\n' \
          | sort \
          | uniq
  }

  deep_summ() {
      suff="${1:-}"
      depth="${2:-4}"
      depth=$((depth - 1))
      summ "$suff"

      for attr in $(attrs_to_check "$suff" | grep -v "types.types"); do
          if [ $depth -eq 0 ]; then
              summ "$attr" | sed -e "s/^/$attr./"
          else
              deep_summ "$attr" "$depth" | sed -e "s/^/$attr./"
          fi
      done
  }

  (
      cd nixpkgs

      #git add .
      #git commit -m "Auto-commit, sorry" || true
      git checkout fixed-lib
      deep_summ > ../fixed-lib

  if diff master fixed-lib; then
      echo "SHALLOW MATCH!"

fcde869e7e lib platform parsing: Fix windows
There is no more `cygwin` OS, but instead a `cygnus` abi. "win32"
and "mingw32" parse as `windows`. Add a 3-part hack because autotools
breaks on explicit abi with windows-like (e.g. "i686-pc-windows-gnu").

Also change cross triples to conform
