assimp: new package

Signed-off-by: Peter Seiderer <ps.report@gmx.net>
----
Changes v1 -> v2:
  - use github helper (thanks to Jörg Krause)

Changes v2 -> v3:
  - add c++ dependency (suggested by Thomas Petazzoni)
  - fix linking problem with builtin zlib (linking code
    with/without '-fpic' compiled, see e.g. [2]), workaround by selecting
    buildroot zlib package (failure detected by Thomas Petazzoni [2])

+	  Open Asset Import Library (assimp) is a portable Open Source
+	  library to import various well-known 3D model formats in a uniform
+	  manner. The most recent version also knows how to export 3d files
+	  and is therefore suitable as a general-purpose 3D model converter.
