BUG=536663
Original issue's description:
> Upgrading binutils to 2.25 for -ggnu-pubnames
>
> To make static_library builds fast we need binutils 2.25 to enable
> -ggnu-pubnames support.
>
> The ehframe-race.patch is removed because it is now included upstream. Dates
> and expected release versions have been added for the remaining patches to make
> it easier to upgrade in the future.
>
> (Also use a precise chroot rather than lucid for building binutils.)
