add basic support for raspberry pi2

Introduce new board symbols for embedded systems, which use
the similar board as basis. As for example raspberry pi and
raspberry pi2.

And some more updates:
Update binutils to 2.25, set gcc 4.9.2 as default.
Update glibc to 2.21, set as default.
Update gdb to 7.8.2.
Update kodi to latest release.
