Are there other places where we try to auto-detect install directory
names?  I don't know of any.

It would be simple to add something like --with-pkgdatadir to
configure.  It sounds like you are talking about a build for a distro;
requiring a configure option for that doesn't sound like a big deal
(as presumably you already need --prefix=/usr among other things).
