    Command-line argument to "Configure" or custom platform template.

    You'll to read the existing files in the "Configurations" directory,
    and cargo-cult a new target definition that meets your needs and
    also adds "shlib_variant".

    Setting "shlib_variant" correctly is all it takes.  The results
    can be verified via "readelf -d".
