cf198e2299 arch: move definition of KERNEL_ARCH to Config.in.<arch> files
Similar to other arch-specific strings, the 'KERNEL_ARCH' variable can be
determined from Config.in.<arch> files.

Besides aligning with similar strings, this also means simplification: the
big 'sed' covers several architectures not even supported by Buildroot.

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.

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.

e543f5a104 arch: remove sh2, sh3 and sh3eb support
This patch removes the sh2, sh3 and sh3eb support, because the user
base is inexistent, and the Linux support for these architectures is
poor. The sh2a support is preserved, because at least one user
expressed interest in this architecture, and is actually using it:

dd712eb31c arch: remove incorrect condition for endian definition on SuperH
Probably due to some copy/paste mistake, Config.in.sh was defining
BR2_ENDIAN to "LITTLE" when the architecture is BR2_x86_64. Due to the
fact that Config.in.sh is never included when we are building for
x86_64, this is a no-op, but is certainly good to clean up.

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.

[Peter: space->tab fix, mipsel64 little endian, mips3 as noted by Arnout]
