Oh, I forgot there's machines that ONLY support Thumb(1) such as cortex-m0. cc @smithp35 

I guess a fundamental question we should answer for llvm-libc is "we claim to support 32b ARM, but we don't specify which minimum target architecture."

I think it would be handy to draw the line at armv6t2+, or even just armv7, but others (@petrhosek @smithp35 ) may feel differently?
