I tested this with an armhf (32 bit) toolchain, and it passes
check-world, and was failing before.
Robert's patch isn't needed on this system. I didn't look into this
subject for long but it seems that SIGBUS on misaligned access (as
typically seen on eg SPARC) requires a 32 bit Linux/ARM kernel, but I
was testing with 32 bit processes and a 64 bit kernel. Apparently 32
bit Linux/ARM has a control /proc/cpu/alignment to select behaviour
(options include emulation, SIGBUS) but 64 bit kernels don't have it
and are happy with misaligned access.
