No, I made that patch myself. That [relro flag is for memory hardening](http://tk-blog.blogspot.com/2009/02/relro-not-so-well-known-memory.html), but isn't compatible with clang or its linker. Does anyone know of any compatible linker flags that accomplish the same thing? Perhaps [PIE](https://en.wikipedia.org/wiki/Position-independent_code#Position-independent_executables) is sufficient, I think relro hurts performance anyways.

[This paper](http://chris.rohlf.googlepages.com/Self-Protecting-GOT.html) looks relevant, but I don't have time to read through it at the moment.
