[RBTREE] Add explicit alignment to sizeof(long) for struct rb_node.
Seems like a strange requirement, but allegedly it was necessary for struct address_space on CRIS, because it otherwise ended up being only byte-aligned. It's harmless enough, and easier to just do it than to prove it isn't necessary... although I really ought to dig out my etrax board and test it some time.
