You keep saying this, but I can't help the feeling it's mostly because 
musl doesn't support it ;-)

No, you don't have to use bindnow to get the effects of relro.  Sure 
there's more parts of the GOT protected with it, but if that's really that 
much more hardened is up for debate.

H.J.'s branch is for _improving_ code on top of the no-plt code, it's not 
replacing it or an alternative for it.
