>Description:

After removing all old pkgs and trying to rebuild everything now that gcc 5.3
is used in base, I ran into this failure in gstreamer 0.10:

libtool: link: gcc -o /ssd/pkgobj/multimedia/gstreamer0.10/work/gstreamer-0.10.36/gst/tmp-introspectyaQJr7/.libs/Gst-0.10 -I/ssd/pkgobj/multimedia/gstreamer0.10/work/.buildlink/include -O2 -pipe -Wl,-R/usr/pkg/lib tmp-introspectyaQJr7/ssd/pkgobj/multimedia/gstreamer0.10/work/gstreamer-0.10.36/gst/tmp-introspectyaQJr7/Gst-0.10.o -Wl,--export-dynamic -pthread -Wl,--export-dynamic  -L/ssd/pkgobj/multimedia/gstreamer0.10/work/.buildlink/lib -L. -L./.libs -lgstreamer-0.10 -lc -lgio-2.0 -lgobject-2.0 -lffi -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lpcre -lintl -lxml2 -lz -llzma -lm -pthread -Wl,-rpath,/usr/pkg/lib -Wl,-rpath,/ssd/pkgobj/multimedia/gstreamer0.10/work/.buildlink/lib
