    Bug 783629 - invert-svg build failure
    
    Fedora hardens its packages by default since Fedora 23 and the home-made
    CC call to build invert-svg needs position-independent code. The flag
    -fPIC is apparently harmless in basic cases since it still builds when
    non-hardened and the doc implies that it would just be ignored if not
    supported by the target machine. As far as I could search, adding it
    should not break other people's builds.
    So what the heck. That's just a temporary build tool, let's add this
    flag and see if others complain!
