Bug#873781: ocaml-gen: FTBFS without ocamlopt: /usr/lib/ocaml/gen/*.a missing

["Aaron M. Ucko" <ucko@debian.org>]

Source: ocaml-gen
Version: 0.4.0.1-1
Severity: important
Justification: fails to build from source

Builds of ocaml-gen for architectures lacking ocamlopt (so far, mips,
ppc64el, s390x, and the non-release architectures hppa, ppc64, and
sparc64) have been failing:

  is_native: ........................................... false
  [...]
  dh_install --fail-missing
  dh_install: Please use dh_missing --list-missing/--fail-missing instead
  dh_install: This feature will be removed in compat 11.
  dh_install: Cannot find (any matches for) "/usr/lib/ocaml/gen/*.a" (tried in ., debian/tmp)

  dh_install: libgen-ocaml-dev missing files: /usr/lib/ocaml/gen/*.a
  dh_install: missing files, aborting

Could you please take a look and either accommodate or explicitly
exclude these architectures?

Thanks!
