[PATCH] ARM: Do not allow unaligned accesses when CONFIG_ALIGNMENT_TRAP

So it sounds like we might not want to enable this blindly across all
architectures. Indeed, on ARM, it encourages the compiler to pack
variables on the stack which leads to the weird and wonderful alignment
situation that has been encountered in this thread.

Interesting. I'm pretty sure it didn't do that when I added the flag.

Anyways making it a CONFIG is fine for me. Just don't set it on ARM. It 
should be set on x86
at least.
