Needed by gimp-liquid-rescale and digikam with clang, otherwise:
graphics/gimp-liquid-rescale/work/.buildlink/lib/liblqr-1.so: undefined reference to `lqr_pixel_get_rgbcol'
graphics/digikam/work/.buildlink/lib/liblqr-1.so: undefined reference to `lqr_carver_read_brightness_grey'
graphics/digikam/work/.buildlink/lib/liblqr-1.so: undefined reference to `lqr_pixel_get_norm'
graphics/digikam/work/.buildlink/lib/liblqr-1.so: undefined reference to `lqr_carver_read_brightness_std'
graphics/digikam/work/.buildlink/lib/liblqr-1.so: undefined reference to `lqr_carver_read_brightness_grey'
