This, please.

When we proposed nuking that from autotools there was some _very_
heated discussion.
It wasn't an issue about relinking, but compat with workflows for
dozens (if not a hundred) of developers.

Mildly related: when using meson, make that you have patchelf or similar tool.
It nukes the RPATH, removing the need to relink the binaries [as it
happens on make install].

Perhaps meson should error out when that's missing?
