The assembler doesn't understand line breaks. You can pass .s files to gcc,
and it will know what to do with them by the file type (.s), and it will also
run the C preprocessor over them, which will let you use line-continuation
backslashes as you have tried above. (Additionally, you can use #include,
#define, #ifdef etc!)
So try using "arm-elf-gcc -c -x assembler-with-cpp" in place of
Can't think of a witty .sigline today....
