Bingo.
This fixes it for me:

Subject: [PATCH libguestfs] build: avoid parallel ocaml/... build failure

A parallel build could fail due to the use in ocaml/examples
of ocaml/guestfs.cmi before it was built.
* Makefile.am (SUBDIRS): Add both ocaml and ocaml/examples,
to ensure they're built in this order, and not in parallel.
* ocaml/Makefile.am (SUBDIRS): Don't define.
