You could build on the device itself, using the native ARM 
compiler here:

You'd have to build the former yourself, the latter is linked 
above.

Depends how it's configured and packaged, but supplying the right 
llvm triple is usually what it takes.  See how it's done for 
Android (llvm triple not needed because llvm is built with it 
above):

Yes, you need those, depending on what you're trying to do.
