Unfortunately, it isn't enough: it doesn't fix biology/chemtool, where
the order isn't caused by gcc but by something in the configure logic:

[*] /usr/pkgsrc/biology/chemtool/work/.wrapper/bin/cc
    /usr/pkgsrc/biology/chemtool/work/.wrapper/bin/cc -O2
    -I/usr/pkg/include -I/usr/include -I/usr/X11R7/include
    -I/usr/X11R7/include/freetype2
    -L/usr/X11R7/lib -R/usr/X11R7/lib
    -o chemtool
    main.o draw.o graph.o chemproc.o undo.o inout.o
    /usr/lib/libintl.so
    -Wl,-R/usr/pkg/lib -Wl,-R/usr/X11R7/lib -pthread
    -L/usr/pkg/lib -L/usr/X11R7/lib
    -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lpangocairo-1.0
    -lXext -lXrender -lXinerama -lXi -lXcursor -lXcomposite -lXdamage
    -lgdk_pixbuf-2.0 -lpangoft2-1.0 -lgio-2.0 -lXfixes -lcairo -lX11
    -lpango-1.0 -lm -lfreetype -lz -lfontconfig
    -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lintl -lX11 -lm

<.> /usr/pkgsrc/biology/chemtool/work/.gcc/bin/gcc -O2
    -I/usr/pkgsrc/biology/chemtool/work/.buildlink/include
    -I/usr/pkgsrc/biology/chemtool/work/.x11-buildlink/include
    -I/usr/pkgsrc/biology/chemtool/work/.x11-buildlink/include/freetype2
    -L/usr/pkgsrc/biology/chemtool/work/.x11-buildlink/lib
    -Wl,-R/usr/X11R7/lib
    -o chemtool
    main.o draw.o graph.o chemproc.o undo.o inout.o
    -Wl,-R/usr/pkg/lib -pthread
    -L/usr/pkgsrc/biology/chemtool/work/.buildlink/lib
    -lintl
    -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lpangocairo-1.0
    -lXext -lXrender -lXinerama -lXi -lXcursor -lXcomposite -lXdamage
    -lgdk_pixbuf-2.0 -lpangoft2-1.0 -lgio-2.0 -lXfixes -lcairo -lX11

    -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lintl -lX11 -lm

Notice that the -L/usr/X11R7/lib -R/usr/X11R7/lib comes before the
correct -Wl,-R options. This no longer causes a warning, but the
-Wl,-R options in the wrapper output are still in the wrong order, and
so the package doesn't link.

I suppose the wrapper is going to have to enforce the ordering of
these.

I have no idea how that (or -R stuff in general) can ever be expected
to work with arbitrary settings of PREFER.foo=pkgsrc...
