Hi Will

Thanks for your great work on arm support. Wouldn't it be better if ARM support was added directly to the Apple swift repo. 
I'm not sure if it's currently possible and what technical challenges we would need to solve to achieve it, i just wold like to know if it has been discussed with swift team?

I've seen blogs about getting it compiled and working on Raspberry PIs, but they seem to have caveats as well as general surprise they got it to work at all.
>> I'm trying to compile Swift on an Nvidia TK1 board, which is an arm7+gpu soc running 32-bit Ubuntu 14, and before I delve too deeply into it (getting some linker errors), I'm wondering if I should bother; I've read that Swift is for 64-bit processors only, but then I read about getting it working on a Raspi where no 64-bit distro is available, AFAIK, so hence my confusion about what 'works' and what doesn't.
