commit 0454408c3f64e7a8032060e71a15282c25264402
Author: Moritz Angermann <moritz.angermann at gmail.com>

    Adds *-cross-ncg flavour.
    
    Our *-cross flavours force -fllvm, this adds flavours for cross
    compilation to x86_64, where we can use our native code generator.
    
    Test Plan: ./validate
