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.
Dave

Matthias, can this patch be included in libffi now that oneiric is open? It's fairly important to have in before we begin armhf bootstrapping.
