Is that supposed to work now, without explicitly invoking sub-generated-headers?
It still doesn't work on current HEAD:

/home/cbe/projects/postgresql/pg/master/build-py3/../src/include/utils/elog.h:71:10: fatal error: utils/errcodes.h: Datei oder Verzeichnis nicht gefunden
#include "utils/errcodes.h"
^~~~~~~~~~~~~~~~~~
compilation terminated.
make[2]: *** [<eingebaut>: plpy_cursorobject.o] Fehler 1
make[2]: Verzeichnis „/home/cbe/projects/postgresql/pg/master/build-py3/src/pl/plpython“ wird verlassen

The other directories we'd need it are contrib/{hstore,jsonb,ltree}_plpython.
