rpath handling in guile-config

[Greg Troxel]

NetBSD pkgsrc applies this patch to get -R passed to the linker.  This
is needed because pkgsrc puts libs in /usr/pkg/lib and this is not in
the default search path.

I realize rpath is contorversial.  It would be nice to support each
os's way, though, but I don't have any non-kludgy ideas.
