What is wrong with my cross compiler?

Question

I am trying to compile a basic program that i can get to cross compile on my mac. I am running Mac OS X Mavericks. My cross compiler is arm-elf-gcc-4.7.3. I wrote a simple test

Answer 1

The compiler was using the wrong assembler. I had to specify the prefix with -B/opt/local/arm-elf-

Answer 2

Reads like the compiler spat out assembly the assembler couldn't read. Check for mismatches.
