linker $ORIGIN processing

[Richard PALO <richard.palo%free.fr@localhost>]

Is there any particularly strong reason why pkgsrc wrappers drop $ORIGIN 
processing from linker RPATHs?

In particular I'm experiencing :
>    (logic) pop:  -Wl,-rpath,$ORIGIN/../lib
>     (arg-pp-main) drop: -Wl,-rpath,$ORIGIN/../lib
>     (logic) pop:  -Wl,-rpath,$ORIGIN
>     (arg-pp-main) drop: -Wl,-rpath,$ORIGIN
in .work.log with _WRAPPER_DEBUG=yes

This comes from mk/wrapper/arg-pp-main:
> ######################################################################
> # Remove rpath options that try to add relative paths to the runtime
> # library search path.  This basically cleans up after lazy programmers
> # who can't write Makefiles.
> ######################################################################
> -R[!/]*|-Wl,-R[!/]*|\
> -Wl,-rpath,[!/]*|-Wl,-rpath-link,[!/]*|-Wl,--rpath,[!/]*)
>         $debug_log $wrapperlog "    (arg-pp-main) drop: $arg"
>         argmatch=yes
>         ;;

Why shouldn't the special case of '$ORIGIN*' not be supported?
