NetBSD didn't break anything; this is the standard way dynamic linking
works for ELF objects.  It struck me as a little bit strange too -- 10
years ago, when it was genuinely new or unusual.  Now that I've managed
to accept it as the norm, I can see that it has decided advantages (if
you read any decent explanation of ELF dependencies and runtime link
paths, and think through it for a bit, I think you will see quickly
what some of them are).

ELF doesn't work quite like a.out did in terms of loading dependencies.
In ELF, there are both a per-executable "run path" which will be searched
to find each named dependency, and, per-dependency, a name.  The run
path is explicit, and is part of the built executable; it is not
implicit in some magical way, pulled from a configuration file in
/etc, or so forth.

-R is how you set the run path in an executable.  That's all.
