7e26b8886b arch/Config.in*: fix attributes order
... to follow the convention: type, default, depends on, select, help.

29e046d6e3 arc/bfin: remove 60x cores
Those cores are not supported in upstream gcc, not even in master.

The only toolchain that supported those core was the 2014R1 ADI
rebuilt toolchain, but we removed it in 311bc13 (toolchain: kill
ADI Blackfin toolchain) because there was too many issues with it.
ADI has not released any newer toolchain since then.

There is little hope for those cores now, so remove them.

Support for those cores has been useless and unusable for a while
without nobody noticing, therefore we intentionally skip adding
Config.in.legacy. This would require keeping code in
arch/Config.in.bfin since the options being removed are inside a
choice...endchoice block.

d9f61fb4ce arch/bfin: internal backend not suitable for some cores
Some cores are not supported by upstream gcc.

Use the newly-introduced symbol to state so, rather than have the
exclusion in the toolchain choice.

d04ea6e4e8 arch: add BR2_READELF_ARCH_NAME hidden config option
This config option corresponds to the string returned by readelf for
the "Machine" field of the ELF header. It will be used to check if the
architecture of binaries built by Buildroot match the target
architecture.

e732bd1f22 bfin: change default to bf532, internal toolchain !bf6xx
The default Blackfin processor in Buildroot isn't supported by
gcc 6.1.0, so use bf532 as default. Disable any bf6xx processors
for internal toolchain users.

4a3f597a0e arch: remove BR2_ARCH_HAS_ATOMICS option
Now that BR2_ARCH_HAS_ATOMICS is no longer used anywhere, we can
remove it from arch/Config.in*, as well as from the documentation.

66d41890ec arch: toolchain: Introduce target CPU revision.
Adds the possibility to have a free-form CPU revision string and append it
to the target CPU. Only Blackfin actually uses this option.

44c04a2b4a 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.

79ee3c1f84 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.
