This may help for applications built wihin the ports framework but
doesn't help if you want to use gcc46 as a general purpose compiler.

I have a nasty feeling this would break i386 emulation on amd64 - if the
i386 executable has an embedded rpath pointing to /lib, it will fail to
find the shared libraries in /lib32.

I agree this is the way to go.  I tried suggesting this in
ports/142226 but it got closed without actually fixing the problem.

(IMO, the whole -rpath approach is backwards - in virtually all cases,
if you link against a library at a specific path, you are going want
to run against that library as well so the default should be to look
there, with something like -rpath only used in the few cases where
that isn't correct).

One of the big advantages of FreeBSD is that it can recompile itself.
Having to install ports to do this would be a massive step backwards
and wouldn't actually solve the underlying problem unless you were
restricted to having no more than one installed toolchain (which has
other problems).
