Split target/Config.in.arch into multiple Config.in.* in arch/
target/Config.in.arch had become too long, and we want to remove the
target/ directory. So let's move it to arch/ and split it this way:
* An initial Config.in that lists the top-level architecture, and
sources the arch-specific Config.in.<arch> files, as well as
Config.in.common (see below)
* One Config.in.<arch> per architecture, listing the CPU families,
ABI choices, etc.
* One Config.in.common that defines the gcc mtune, march, mcpu values
and other hidden options.

Split target/Config.in.arch into multiple Config.in.* in arch/
target/Config.in.arch had become too long, and we want to remove the
target/ directory. So let's move it to arch/ and split it this way:
* An initial Config.in that lists the top-level architecture, and
sources the arch-specific Config.in.<arch> files, as well as
Config.in.common (see below)
* One Config.in.<arch> per architecture, listing the CPU families,
ABI choices, etc.
* One Config.in.common that defines the gcc mtune, march, mcpu values
and other hidden options.

Split target/Config.in.arch into multiple Config.in.* in arch/
target/Config.in.arch had become too long, and we want to remove the
target/ directory. So let's move it to arch/ and split it this way:
* An initial Config.in that lists the top-level architecture, and
sources the arch-specific Config.in.<arch> files, as well as
Config.in.common (see below)
* One Config.in.<arch> per architecture, listing the CPU families,
ABI choices, etc.
* One Config.in.common that defines the gcc mtune, march, mcpu values
and other hidden options.

arch: introduce minimal required gcc version
Some CPU variants require that a recent-enough gcc be selected. For
example, ARM's cortex-a35 requires gcc-5, while cortex-a73 requires
gcc-7. Same goes for other architectures, of course.
Currently, we hard-code every such conditions in the gcc version choice,
as well as in the individual external toolchains.
However, as we add even more CPU variants, the conditions are getting
more and more complex to write and maintain.
Introduce new symbols, that architectures can select if they have a
specific requirement on the gcc version. gcc and external toolchains
can then properly depend on those symbols.
The burden of maintaining the requirements on the gcc version now falls
down to the architeture, instead of being split up in gcc and all the
external toolchains.
As the oldest gcc version to handle, we can either choose gcc-4.9, as
the oldest version we support in our internal toolchain, or choose
gcc-4.8, as the oldest external toolchain we support (except for the
custom ones, but they'll be handled specifically in upcoming changes).
We choose to go back up to gcc-4.8.

arch: improve definition of gcc mtune, mcpu, etc.
As suggested by Yann E. Morin, there is a better way than our current
big Config.in.common to define the gcc mtune, mcpu, march,
etc. values. We can split the setting of those values in each
architecture file, which makes a lot more sense.
Therefore, the Config.in file now creates empty kconfig variables
BR2_ARCH, BR2_ENDIAN, BR2_GCC_TARGET_TUNE, BR2_GCC_TARGET_ARCH,
BR2_GCC_TARGET_ABI and BR2_GCC_TARGET_CPU. The values of those
variables are set by the individual Config.in.<arch> files. This is
possible because such files are now only conditionally included
depending on the top-level architecture that has been selected.

Buildroot already has the BR2_GCC_TARGET_{TUNE,ARCH,ABI,CPU} hidden
kconfig strings that allow per-architecture Config.in files to feed
the appropriate values of --with-{tune,arch,abi-cpu} when building
gcc, or the appropriate flags for the external toolchain wrapper.
This commit has two additional options:
BR2_GCC_TARGET_{FPU,FLOAT_ABI}, that allows to define the
--with-{fpu,float} gcc configure options for the internal backend, or
the -m{fpu,float-abi} options for the flags of the external toolchain
wrapper.

arch: merge Config.in.aarch64 into Config.in.arm
The 64 bits ARM processors are capable of running 32 bits ARM code, and
some platforms are indeed using this capability. Due to this, if we were
to keep the separation between Config.in.aarch64 and Config.in.arm, we
would have to duplicate the definition of all 64-bits capable ARM cores
into both files.
Instead of going down this route, let's take the same route as the x86
one: a single Config.in.x86 file, used for both x86 32 bits and x86 64
bits, with the appropriate logic to only show the relevant cores
depending on which architecture is selected.
In order to do this, we:
- Make the "ARM instruction set" choice only visible on ARM 32 bits,
since we currently don't support ARM vs. Thumb on AArch64.
- Add the relevant values for the BR2_ARCH option.
- Add the relevant values for the BR2_ENDIAN option.
- Make the "aapcs-linux" BR2_GCC_TARGET_ABI value only used on ARM 32
bits, since this ABI doesn't mean anything on AArch64.
- Make the BR2_GCC_TARGET_FPU option depends on ARM 32 bits, since
there is no -mfpu option on AArch64.

Config.in.common (see below)
* One Config.in.<arch> per architecture, listing the CPU families,

* One Config.in.common that defines the gcc mtune, march, mcpu values
and other hidden options.

Split target/Config.in.arch into multiple Config.in.* in arch/
target/Config.in.arch had become too long, and we want to remove the
target/ directory. So let's move it to arch/ and split it this way:
* An initial Config.in that lists the top-level architecture, and
sources the arch-specific Config.in.<arch> files, as well as
Config.in.common (see below)
* One Config.in.<arch> per architecture, listing the CPU families,
ABI choices, etc.
* One Config.in.common that defines the gcc mtune, march, mcpu values
and other hidden options.

arch: improve definition of gcc mtune, mcpu, etc.
As suggested by Yann E. Morin, there is a better way than our current
big Config.in.common to define the gcc mtune, mcpu, march,
etc. values. We can split the setting of those values in each
architecture file, which makes a lot more sense.
Therefore, the Config.in file now creates empty kconfig variables
BR2_ARCH, BR2_ENDIAN, BR2_GCC_TARGET_TUNE, BR2_GCC_TARGET_ARCH,
BR2_GCC_TARGET_ABI and BR2_GCC_TARGET_CPU. The values of those
variables are set by the individual Config.in.<arch> files. This is
possible because such files are now only conditionally included
depending on the top-level architecture that has been selected.
