I was overconfident: the patch broke everything, because
Automake-generated makefiles typically try to mkdir $localstatedir:

So I just reverted it, and I think we’re stuck with the status quo until
someone has a better idea.

For the longer term, we could submit an Automake patch such that it
doesn’t insist on creating $localstatedir et al.
