mov r7, r0 puts the syscall nr into r7.  i haven't looked at the
alignment, though :-\

"With EABI, 64-bit function parameters passed in registers are aligned
to an even-numbered register instead of using the next available
pair."

what output does:

qemu-arm -strace hello

give? (run on your i386 after cross-compiling)

did you compile this with the 2.18 binutils?  my qemu-arm is happy
with my simple hello program.  even does writeln(2/3) properly.
