f472dd7652 Revert "Revert "gcc, binutils: Get rid of 32-bit ARM configure flag exception""
And there's more reverts too. The previous commmit
d838afbc9376bdadb8c690eb00b425f3eeccdf2d to gnu-config finally solves
it!

This reverts commit 3ed545ab31.

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.

Revert "gcc, binutils: Get rid of 32-bit ARM configure flag exception"
This commit breaks native armv7l-linux builds. Revert it until it can
be root-caused. This reversion does not affect other platforms or
cross-compiling.

This reverts commit 0f5c804631.

1c1207220f gcc: Refactor treatment of configure flags
Previously configureFlags was defined as one giant interpolated string.
Here we refactor this definition to instead use the usual stdenv string
combinators. This seems more in-line with the average nixpkgs expression
and it seems a bit more natural to things of these as lists of flags
rather than monolithic strings.

4d4f94cde4 treewide: Depend on targetPackages.stdenv.cc.bintools instead of binutils directly
One should do this when needed executables at run time. It is more
honest and cross-friendly than refering to binutils directly, if one
neeeds the default binary tools for the target platform, rather than
binutils in particular.
