The ordering is not good: you can't remove this "select" until all the
toolchain components have C-SKY support added. So this patch should
come later in the series, it should actually be one of the last patch,
and should be: "arch/csky: enable internal toolchain backend" or
something like that.

This should be a separate patch.
