Fails to build on win32:

  LINK  arm-softmmu/qemu-system-arm.exe
arch_init.o: In function `do_compress_ram_page':
/home/petmay01/linaro/qemu-for-merges/arch_init.c:879: undefined
reference to `___sync_fetch_and_add_8'
collect2: ld returned 1 exit status

It's not valid to try to do atomic operations on a type
that's larger than the native pointer type. (This will also
cause compile issues on ppc32.) Unfortunately we don't
currently have a way to make this a compile failure on
normal 32-bit x86 setups...
