libffi: back-port support for ARC
Support for ARC CPUs was added in libffi after 3.0.13 vesion was cut and up until now no new release has been done. So to enale libffi on ARC we need this set of patches. These are corrsponding commits in libffi: * b082e15091961373c03d10ed0251f619ebb6ed76 - Add ARC support * 0f8690a84c874ec09a090c8c6adfb93c594acac6 - Rebuild for ARC additions * d918d47809c174d62283306b282749f8db93661f - arc: Fix build error The first patch was modified a bit (cut changelog part) to accomodate changes not related to ARC between 3.0.14 and changes in question.

+Subject: [PATCH 1/3] Add ARC support
+
+This adds support for the ARC architecture to libffi. DesignWare ARC
+is a family of processors from Synopsys, Inc.
+
+This patch has been tested on a little-endian system and passes
+the testsuite.
