sparc: Define ARCH_SLAB_MINALIGN
Because SLOB fancies being different, the default minimum alignment is only "unsigned long" instead of SLAB/SLUB where the default is "unsigned long long" The inconsistency makes no sense and is asking for trouble, but define ARCH_SLAB_MINALIGN to get it right in all cases even after they fix the inconsistency.
