commit 915fa39d0f927712f7a468c0a2f4497aef0a3b0f
Author: Sebastian Hahn <sebastian@xxxxxxxxxxxxxx>
Date:   Sat Apr 29 08:51:51 2017 +0200

    Add --enable-rust configure switch
    
    Introduce a way to optionally enable Rust integration for our builds. No
    actual Rust code is added yet and specifying the flag has no effect
    other than failing the build if rustc and cargo are unavailable.
