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.
