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.
