Original issue's description:
> Change v8_snapshot_toolchain to be a GN build arg.
>
> It is likely that CrOS and other distros will want to be
> able to build the v8 snapshot with a custom toolchain.
>
> This CL makes snapshot_toolchain a declared build arg, and
> renames it to v8_snapshot_toolchain to minimize the risk
> of a name collision.

# TODO(GYP): For now we only support 32-bit little-endian target builds from an
