I don't see that rule in my ompi/include/Makefile. I only have a couple of
mentions of mpi.h.in:
----✂----
DIST_COMMON = $(top_srcdir)/Makefile.ompi-rules \
$(srcdir)/ompi/Makefile.am $(srcdir)/Makefile.in \

$(srcdir)/mpif-config.h.in $(am__include_HEADERS_DIST) \

am__tagged_files = $(HEADERS) $(SOURCES) $(TAGS_FILES) $(LISP)mpi.h.in

stamp-h2: $(srcdir)/mpi.h.in $(top_builddir)/config.status
@rm -f stamp-h2
cd $(top_builddir) && $(SHELL) ./config.status ompi/include/mpi.h

Maybe the rule in your version of ompi/include/Makefile comes from an older,
buggy version of automake?

I don't see $(AUTOHEADER) being invoked by make when I run the commands you
listed (with "sleep 1" changed to "sleep 5" to be certain):
