Fix alignment fault on ARM when running modules. With out an explicit linker file gcc4.2.1 will half word align __bss_start's value. The word dereference will crash hello_world.

Hi,
I'll attach a zip of a quick update for h4-2420 which I did against git just now. It needs more work to merge but at least works. Its probably on the edge for size. A 2430 merge and more of a fix up could come later.
Regards, Richard W.
