-   When going via-C, the mangler arranges that we only generate
-   relative relocations between symbols in the same segment (the text

    Somewhere between binutils-2.16.1 and binutils-2.16.91.0.6,
    support for 64-bit PC-relative relocations was added, so maybe this
    hackery can go away sometime.
