When building in thumb mode, the conditional instructions are supposed
to have 'it' instructions preceding them (unless the assembler is
set to automatically inject such).
This fixes building with clang/llvm 3.9, while the build passed
with clang/llvm 3.8 (unsure whether it actually injected such instructions
though)
