When src/test/modules is compiled directly after running ./configure,
make complains about utils/errcodes.h missing:
In file included from worker_spi.c:23:
In file included from ../../../../src/include/postgres.h:48:
../../../../src/include/utils/elog.h:69:10: fatal error:
'utils/errcodes.h' file not found
#include "utils/errcodes.h"

Shouldn't src/test/modules/Makefile includes .PHONY with
submake-errcodes like for example in the patch attached?
