Add kalimba as a platform.

Browse Source 
This change comprises of additions and some minor changes in order that
"kalimba" is listed as a supported platform and that debugging any
kalimbas results in PlatformKalimba being associated with the target.

The changes are as follows:

* The PlatformKalimba implementation itself
* A tweak to ArchSpec
* .note parsing for Kalimba in ObjectFileELF.cpp
* Plugin registration
* Makefile additions
