Several of these are interesting.

Why do you think the code is hard to read?  ;-)

In theory: no run paths for paths that the runtime linker searches by
default.  Otherwise, rpaths for all libraries we link directly against.
(Omitting the minor detail that we care about the difference of
uninstalled vs. installed locations, for simplicity.)

Now, in theory, theory and reality are the same.  And all GNU/Linux
distributions have the same multilib layout. :-/
