darktable in unstable and experimental fails to build with gcc-9, due
to openmp related changes.

This is known, and fixed upstream in git master.  It will probably be
at least another month or so before a release. There is more than one
merge request upstream that would have to be backported to do this
nicely.

Currently the options seem to be

- - force the build to use gcc-8

- - package a git snapshot, and (presumably) keep it out of testing

- - take on faith a 5k line patch opensuse is using; that patch only
  mentions one pull request, so I don't know if it is a complete
  solution.
