recipes: inherit autotools-brokensep or set B = ${S} for failing recipes

* this 'marks' broken recipes and allows to get resonable report from world builds
  but ideally we should fix the issues in the recipes or the components.

* I'll keep this on ML for a while to see if we find some volunteers to fix their
  favourite recipes
