Ard: Without this change, GCC5 LTO can pass build. With it, what difference will be in the generated image? Original way may generate the wrong image, or new way will generate the smaller image?

Since we now invoke GCC as the linker, we can start passing the CC_FLAGS to the linker as well, with only minor surgery. This does not bother non-LTO links at all, and forces the LTO links to use the correct settings.
