a20cb38659 arch: add support for "jaguar" AMD CPU optimisations
AMD Jaguar ( https://en.wikipedia.org/wiki/Jaguar_%28microarchitecture%29 ) is
suddenly a popular architecture since it is used in the PS4 and the XBox One.
Many embedded systems are also likely to use it in the next years.

This patch adds support for GCC architecture-specific optimisations and
tuning for these CPUs.
These optimizations are available with GCC 4.8+.

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.
