[swift-dev] R_ARM_GOT_PREL error when building Swift on Pi from source

I was able to get Swift running on my Raspberry Pi using a variant of the instructions at <http://dev.iachieved.it/iachievedit/open-source-swift-on-raspberry-pi-2/> but sadly the packages I’ve found haven’t been updated for Swift 2.2 (so things like `associatedtype` don’t work nicely between Mac and Linux).
So, I thought I’d try building from source again hoping that the previous failure was resolved. But I’m still hitting the unimplemented relocation issue in LLVM’s RuntimeDyldELF.cpp, in RuntimeDyldELF::resolveARMRelocation(), where the relocation type that is being requested is R_ARM_GOT_PREL.
I thought I read in my last go-round on this that this was a regression in LLVM, but I’m not finding a pointer to this now, so maybe I’m misremembering.
Is there a trick to avoiding this issue in LLVM, or an existing patch somewhere that I can cherry-pick?
