    Add ./configure-script with presets for common systems
    
    After quite a few requests and a bit of reflection on my behalf I've
    decided to add a very simple ./configure-script that automatically
    modifies config.mk to make it fit for common systems.
    
    Even though it's reasonable to simply have out-commentable options
    in the config.mk, it is admittedly more convenient to have such a
    script available, especially to accomodate more systems along the way.
    
    uname(1) is Posix compliant and this ./configure-script is in no way
    comparable to the horrible autoconf-insanity and won't take an eternity
    to run. It's also completely optional and merely a
    quality-of-life-addition for those working with libgrapheme manually.
