 This would prevent pullup according to current releng policies.
 We can make exceptions and document them carefully in case that are
 considered extremely important, as the main idea behind the rule is
 to prevent binaries compiled for newer netbsd-8 to not work on (say)
 NetBSD 8.1.
 This change is userland visible, and kmem users may break. It is not clear
 to me if the what exactly the amount of breakage would be and if the
 benefit of the change would be higher.
 I have not followed the thread closely from the beginning, is this about
 ld.elf_so's ORIGIN handling? I thought we don't rely on that in pkgsrc
 rust anyway (past bootstrap).
