...which is not really normal.  In SVR4, rpaths can be specified when
linking a library, as well as an executable.

However, something makes me think I saw this working in NetBSD once(!), on
alpha.  This just needs an empirical test... link library1, link dependent
library2 with rpath to library1, and link executable with rpath to library2
only ... then ldd the executable.
