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.
