That's because newer expat.h depends on features defined in expat_config.h. In this particular case XML_SetAllocTrackerActivationThreshold is guarded with "# if defined(XML_DTD) || (defined(XML_GE) && XML_GE == 1)", and XML_DTD, XML_GE, and XML_GE are defined in expat_config.h.
It should be possible to add some builtin.mk checks to handle this, gated on whichever release started requiring it.
I can commit PREFER.expat=pkgsrc solution, if no objection.
I think we should do this for now, and evaluate a more general builtin.mk approach after the freeze.
