Building storage/lwlocknames.h?

Hi,

the Debian package build compiles plpython twice, once for python 2 in
the main build, and then for python 3 in an extra run. In order not to
waste too much time, we have this recipe in there:

stamp/build-py3: stamp/configure-build-py3
$(MAKE) -C build-py3/src/backend/ submake-errcodes
$(MAKE) -C build-py3/src/pl/plpython
$(MAKE) -C build-py3/contrib/hstore_plpython

So far that worked, but on 9.6 head there's now a problem with
storage/lwlocknames.h:

Can we have a "submake-lwlocknames" build target like there already is
for submake-errcodes? Reading the Makefile I could not see how to
manually trigger this individually.

Thanks,
Christoph
