Sid Manning 42064e5b60 * Add relocation reference support for Hexagon and PowerPC. 
- Hexagon has many relocation types, this patch covers just
      a subset, more will be added.
    - PowerPC support was added so that we can verify mixed endian
      environments.
  * Add some basic test cases
  * Update ldd-core to accept -endian flag
