eda11417be m68k: remove BR2_GCC_TARGET_ARCH
Setting BR2_GCC_TARGET_ARCH is possible, but breaks
external toolchain users. m68k/cf defconfigs just
working without it.

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.

db5e6d6c14 arch/m68k: get rid of BR2_GCC_TARGET_TUNE
On m68k, we are passing the exact same values of BR2_GCC_TARGET_ARCH
and BR2_GCC_TARGET_TUNE, which is redundant. Therefore, this commit
removes the usage of BR2_GCC_TARGET_TUNE on m68k.

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.
