I agree that the current location is a bit ugly (and so is e.g.
/etc/ld.so.cache and /.readahead).

That said, I don't think libdir is appropriate as this data is not
under the control of the package manager (as it is generated at
install-time rather than at build-time, it would for instance not be
suitable for sharing between hosts). I guess localstatedir would be
another alternative, but the problem there is that it is not
(necessarily) available during early boot when this db is needed.
