The issue has to do with explicit -I/usr/include/dbXY in CFLAGS and implicit /usr/include for
	#include <db.h>
when /usr/include/dbXY is not present or is empty and “system db” != dbXY.

The wrong <db.h> (with different #define values) can be included, leading
to very bizarre/scary rpmdb failures at run time.

A proper fix to limit the include search somehow is a huge PITA (and so I haven’t bothered).

But I see rpmdb issue(s) frequently while developing RPM on various platforms that
aren’t yet setup correctly, sigh.
