It isn't necessary for building various components in pc-bios/optionrom, as evidenced by looking at actually used link flags there. Alpine Linux for x86_64 does not ship with 32bit libgcc, but its gcc is otherwise perfectly capable of building firmwares in pc-bios/optionrom dir. Make configure recognize this situation. Keep requiring functional -lgcc in other places.
