Setting up a cross compile system is always more complicated than
compiling natively.
It is possible to do so (we do it here locally for PNaCl project, for
example, going from X86 to ARM),
but it requires setup for things like llvm-gcc, the target libc and
other target libraries you are linking against...
not to mention a cross compiling binutils, and its irritating to get "right"

It might be easiest to buy a cheap ARM box and compile natively using ARM gcc...
