Thank you!

I did the initial port, I expect the ‘ret_guard’ protections need to be turned off in the linker or compiler, I don’t have the time to look too deeply atm,...

Just read [clang-local](https://man.openbsd.org/clang-local) `clang includes the retguard security feature on amd64, arm64, mips64, powerpc and powerpc64. This feature can be disabled with the -fno-ret-protector or -fno-stack-protector options.` Should be enough...

It's great to see OpenBSD working again! I wish you well with the rest of the Mirage ecosystem.
