[patch] Forward the -O options to the linker

It is fairly common for -O to be passed to clang when linking and both
bfd and gold support -O options, but currently the driver doesn't
translate it and projects have to use -Wl,-O if they want to enable
those options. In fact, our own build pass -O3, but not -Wl,-O.

The attached patch translates and forwards the -O options to the linker.
