I had a look today at DT_RELR again, and found I need to do some work
in the linker.  Just keeping addresses of relative relocs isn't
enough, because data addresses can change between ppc64_elf_size_stubs
and ppc64_elf_build_stubs.  Anyway, the reason for the email is to
inform anyone playing with DT_RELR on powerpc64 that the current
support is definitely experimental!  Also, you might like to apply the
attached patch to gitlab.com/x86-glibc/glibc users/hjl/relr/master
branch.  glibc regressions went from 574 to 17.
