So this seems like a pointless exercise from the Debian packaging point of view. I mean, why bother to build the databases if one needs them to build? Is this correct, or am I missing something?

You are correct.  Trying to build the interface databases from source doesn't help you avoid any bootstrapping issues.

(When we port CCL to a new system, we cross-compile interface databases for the new target in an ad-hoc way.)
