Add "options ARM32_DISABLE_ALIGNMENT_FAULTS" to forcibly disable alignment fault checking if necessary. This option gets the acorn32 port working again. XXX: Richard Earnshaw suggested enabling alignment faults for XXX: userland only on acorn32. Need to investigate this.

# $NetBSD: std.acorn32,v 1.2 2003/11/05 12:53:15 scw Exp $
Initial commit of the splitting off of arch/acorn32 from arch/arm32. The IOMD/VIDC combination is now moved to arch/arm/iomd together. These files still need a lot of cleaning up :( .... esp. the RC7500 support that is still dormant in it; this needs either to be removed or split out for RC7500's ``VIDC'' video/audio variant. Apart from the RC7500 support wich is still in arch/arm32 the iomd,vidc,riscpc and podulebus subdirectories of arch/arm32 can be removed. This split still uses some small parts of arch/arm32 .... those are the MI parts that haven't been moved yet. RiscPC/A7000 have been tested and confirmed to build as should NC.

# Since the hardware is not capable of half-word loads/stores,
# Acorn machines and alignment faults do not play nice together.
