No, it doesn't have to run code for x86_64-netbsd. I can build the LLVM
libraries for i386-linux, link it, run it and it will work. Sure, I
likely have to provide it with Linux compatible header files etc like
using cross-compilation in general. My point remains that just because I
am cross-compiling doesn't mean I can't execute JIT code.
