PATCH 1/1 init/Kconfig: make CC_OPTIMIZE_FOR_DEBUGGING visible only for GCC

Currently CC_OPTIMIZE_FOR_DEBUGGING is only able to build with GCC. For clang, -Og optimization level could break kernel build. So make CC_OPTIMIZE_FOR_DEBUGGING visible only for GCC.

I squashed this into the previous patch in the kbuild tree.

Thanks!
