if you pass --enable-new-dtags, you will get the same on all distros.

the use of DT_RPATH ("old-dtags") is deprecated, that's what LD.SO(8)
says. that is distro independent [1]. coincidently the new dtags have
just become the default in debian. iirc, gentoo also does it like this.
others will probably follow.

without the override, it's not possible to make use of something similar
to LD_LIBRARY_PATH=$HOME/.gnucap/my_plugins. so that qualifies as
"broken".

DT_RUNPATH and LD_LIBRARY_PATH have always worked for me. it will be
hard to improve. is there a (reasonable) platform that does not support
it?

imo we should add the "--enable-new-dtags" to "plugpath+" and be done
(for quite a while). it will very likely not break any existing
installs.

wouldn't it be possible to start a different approach as a plugin? that
might make sense in particular if it changes the current dlopen
behaviour...
