Comment:
Note the issue is kind of fun, because Void installs stuff as non-root, but mapped to root via userns, so the kernel doesn't give out its "you are root, so you're exempt from setuid wiping" thing.

And Meson's own testsuite didn't catch that, because our test for the setuid functionality working, didn't include a binary with a build rpath to be deleted.
