So it appears. I copied the rule that modifies errcodes.h, but clearly
that's not enough. I think I might need to steal and adapt the
following logic from src/backend/catalog/Makefile:

# locations of headers that genbki.pl needs to read
pg_includes = -I$(top_srcdir)/src/include/catalog
-I$(top_builddir)/src/include/catalog

I'll go test that now.
