Bug description:
  Libffi (3.0.9) does not explicitly support calls to variadic functions - however for most architectures they tend to work.
  For armhf this is not the case - variadic calls drop back to the armel ABI; to support this I added a new API to libffi to explicitly support calling variadic functions.

  The attached patch was accepted upstream and will land sometime after
  3.0.10; we might want to merge it in sooner if we need armhf support
  sooner.

  Note that programs that use libffi will also need changing for their
  variadic calls to work - but nothing that already works should break.
