Log Message:
-----------
Add use_rtld_origin parameter to control use of rtld ORIGIN
feature when shared libraries are in use.
This is currently commented out, and may be fully implemented later.

Requires support from the runtime linker; most modern ELF systems
support the ORIGIN feature, and it's used by KDE, Firefox and others.

If the user passes use_rtld_origin=true on the scons command line,
the RPATH will use the ELF runtime linker's ORIGIN feature; shared
libraries will be searched relative to the executable's path.

This feature will enable us to build the world once, without relinking
whenever DESTDIR is changed.
