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.

uclibc: Provide a more stable location for source.
At the upstream URL at http://git.uclibc.org/uClibc/snapshot/, older
versions are dropped at a regular basis. Unfortunately the tarball
"uClibc-20150131.tar.bz2" has already been deleted from that directory
and I didn't find a mirror providing the same file.

So I've switched it to use fetchzip from the cgit site instead of using
fetchgit directly. The reason why I didn't use fetchgit is that we'd
need need git, which depends (indirectly? not sure, haven't checked) on
libiconv and that in turn triggers an assertion if we're on Linux and
are cross-building using uclibc.

c375a6744b Updating uclibc (snapshots).
I also update the way the configuration is generated, so it works for
our ARM EABI, armv5tel.

We will have to enable the FPU for armv6 and beyond.

37fce10f9b Adding native threads support unconditionally to uclibc,

Let's see if this breaks anything; I'm changing this to make comtrend.nix work
(kernel 2.4).

fb6adb13ac Updating busybox. I left only a single busybox in its directory. The others, coming from the old
cross-building nixpkgs implementation, were not referenced anywhere.

This new busybox builds natively, and also cross-builds with uclibc.

I updated the uclibc config with a busybox defconfig requirement (something about RPC).

I made the gcc-cross-wrapper properly set the dynamic loader to programs.

After this, 'qemu-arm' can run the dynamically linked busybox cross built for armv5tel--linux-gnueabi.

4164de326a Making the cross-builds work with uclibc. There is no easy way of switching

4b27d28701 Porting changes from stdenv-updates into this branch.
This comes from:
svn diff  ^/nixpkgs/trunk/@18255 ^/nixpkgs/branches/stdenv-updates/ > diff
patch -p0 < diff
and then adding into svn all files new from the patch.

trunk@18255 comes from the last time I updated stdenv-updates from trunk.
