    sysdev-thirdparty: few fixes
    libz.so.2.0.0 => libasound.so.2.0.0
    DESTDIR can't be a relative path
    /usr/share/alsa/pcm/default.conf is needed else alsa will complain about
    not finding the default pcm output.
    libao actually depends on alsa-lib, we need to set CPPFLAGS and LDFLAGS.
    vorbis-tools 1.4.0 is the latest version.
    libusb => make
