I agree, it will be cleaner.

There might be problems with mixing shared libraries
and/or static libraries (object files) compiled for different OS/ABI.
This definitely needs a test.

I already went into some trouble, see 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338603

Maybe rebuilt of all packages or carefull temporary hack
in binutils will be needed.

In the same time, we could change name of our default
program interpreter (ld.so). Its location should be unique
between all (at least Debian) ports.

What about /lib/ld-kfreebsd-i386.so.2 and /lib/ld-kfreebsd-amd64.so.2 ?
