Upgrade binutils and gold.
upgrade binutils-2.19 to binutils-2.20.1 upgrade gold to a relatively new version binutils-20100303 Before, both binutils and gold were built from binutils-2.19. Now binutils will be built from binutils-2.20.1 and gold will be built from binutils-20100303. Change-Id: Ibd0130756723337d2b4783d5b1d5e5b02a1adc83
