Newer versions of the linker suggest --rpath-link, which is actually a
better choice.

--rpath is a linker option.  As such, you have to use -Wl, or -Xlinker
to get it only to the linker.

Yep, it doesn't make sense to me to pass options like that.  The
option was --rpath, after all, not -frpath or anything that resembled
a cc1plus option.
