Add support for Blackfin Taken upstream from https://github.com/atgreen/libffi/commit/213ed15c70e72d666154c08e2b41dae3f61f20d3. Will be part of the upcoming 3.0.12 release. We have kept the part of the patches changing configure and Makefile.in in order to avoid having to autoreconf the package, which requires autoconf 2.68. Code written by Alexandre Keunecke.
