>Description:
when buildlink3 is being used, binaries linked against gcc shared
libraries can't find them at runtime because buildlink3 has clobbered
the one of the rpath arguments.

from .work.log of a buildlink3 package:

[*] /work/pkgbuild/archivers/unrar/work/.buildlink/bin/g++ -o unrar

 -L/work/pkgbuild/archivers/unrar/work/.buildlink/gcc-2.95.3/lib 
-L/work/pkgbuild/archivers/unrar/work/.buildlink/lib

-Wl,-R/usr/pkg/gcc-2.95.3/lib is missing from the command after
buildlink3.

without buildlink3, the rpath above is passed to g++ and it works:

        libstdc++.so.4.0 =>      /usr/pkg/gcc-2.95.3/lib/libstdc++.so.4.0

this is also confirmed with devel/ncurses which uses buildlink3 and
libtool.

I'm send-pr'ing this because it is critical this gets fixed on the
2004Q2 branch.
