Yeah- shrink-rpath is doing the damage.

I may have to test that- but it's still definitely something that breaks on my
machine.

On an ARM system, install vim_configurable (doesn't matter which configuration)-
it'll segfault after being stripped by patchelf. I can't remember off the top of
my head any other examples, but I know that one certainly breaks.

The most I can find is https://github.com/NixOS/patchelf/issues/8 which may or
may not be related as it affects Fedora. My solution is to disable patchelf
since it's breaking things without good reason.
