arch/x86: get rid of BR2_GCC_TARGET_TUNE
According to the gcc documentation, -march implies -mtune on x86, so defining both BR2_GCC_TARGET_ARCH and BR2_GCC_TARGET_TUNE is redundant. Therefore, this commit removes the definition of BR2_GCC_TARGET_TUNE on x86. However, while doing so, it adds one new case for BR2_GCC_TARGET_ARCH: using -march=generic when BR2_x86_generic is selected.
