If the defines vary between target triples, you might need to pass the ArchSpec into the function from the process. Then the code can check the ArchSpec.GetTriple() (which gives you an llvm::Triple) so you can check for FreeBSD/Linux and it can do the right thing for both.
There will be remote debugging soon in the future and these DYLD plug-ins are not tied to the current host are they?
