If the bdb patch defines a variable and openldap accesses it, patched
openldap + unpatched bdb should fail at link time.
I don't remember if the bdb patch is harmless to a caller which does not
know about the patch - if so, openldap could set the bdb variable and
bdb could invoke the new behaviour only if the variable is true.
