Looking harder, there was context in the commit message that wasn't
present as a comment in the Makefile.  I now believe that

  - the version of expat in NetBSD 10 has always been good enough
  - NetBSD's install process  erroneously did not install expat_config.h
  - a pullup to do the install happened recently

That leaves us either solving Problem A or B:

A)  all of

   - 1) OR
     + i) adjust patterns in python3

     + ii) adjust expat's builtin.mk to accept builtin expat.h only if
       expat_config.h is present.  Just adding expat_config.h to the
       header variable does not work.

   - 2) do bulk builds for pkgsrc users with netbsd-10 from after the
     pullup

B)

   - 1) python, when built with pkgsrc expat, appears to crash during xml
     operations (qgis plugin loading).  Based on struggling with macOS,
     I see that there are multiple -I args and suspect this results in
     the build seeing some mix of expat versions -- but I'm guessing.
     Fix this.

Personally, I've done A)1)i) and A)2) locally, so programs run ok for
me, but that's not going to help other people.
