commit 12bd14032cc4a687b4008ae3bad50bf637be3462

    Force pkg-config --static for fbsplash checks
    
    Since suspend links with libfbsplashrender statically, static libs
    should be taken from pkg-config output. Otherwise linking fails
    with unresolved symbols due to incomplete library list.
    See Gentoo bug 556954 for details.
