`relro` hardening ignored? #216

Can you provide context to why is relro ignored?

(i assume that it's set to be ignored by upstream i don't have experience with OpenRISC 1000 and would like to add note to NixOS packaging with reasoning)

relro is ignored because there are no relocations in the linked ELF binary, so there is nothing to put in a relro section. It is not related to the architecture being OpenRISC 1000.
