-You need to have gold with plugin support and build the LLVMgold plugin.
-Check whether you have gold running ``/usr/bin/ld -v``. It will report "GNU
-gold" or else "GNU ld" if not. If you have gold, check for plugin support
-by running ``/usr/bin/ld -plugin``. If it complains "missing argument" then
