John Ericson ba52ae5048 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.

Will Dietz f14ff86ec9 bintools-wrapper: fix breakage on aarch64, where "isArm" is false

Daniel Barlow 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

John Ericson 3a50395ef2 {bintools,cc}-wrapper: extraPackages should be depsTargetTargetPropagated
They are libraries used by programs built with these tools, not used by the
tools themselves.

John Ericson cc44e04472 bintools-wrapper: Define fallback default emulation
This ensures we by-default cross-compile to the intended platform.

John Ericson 99806c5e12 bintools-wrapper: Create man and info outputs propagated underlying ones
These will be installed if the wrappers are. The wrappers aren't very
good to install, but that's another matter.

John Ericson 8e557ed2c5 bintools-wrapper: Init
Factor a bintools (i.e. binutils / cctools) wrapper out of cc-wrapper. While
only LD is wrapped, the setup hook defines environment variables on behalf of
other utilites.
