I guess it would also be nice if this was conditionalized in some way so
that it only triggered if one was trying to do a multilib build (or, at
least, had a TARGET_ARCH which supported multiple different wordsizes).
I don't especially want to have all the headers on, say, arm wrapped in
wordsize conditionals since the word size is basically invariant there.
