Remove Cell Broadband Engine debugging support

This patch implements removal of Cell/B.E. support, including
- Support for the spu-*-* target
- Support for native stand-alone SPU debugging
- Support for integrated debugging of combined PPU/SPU applications
- Remote debugging (gdbserver) support for all the above.

The patch also removes the TARGET_OBJECT_SPU target object type,
as this is available only on Cell/B.E. targets, including
- Native Linux support
- Core file support (including core file generation)
- Remote target support, including removal of the qXfer:spu:read
  and qXfer:spu:write remote protocal packets and associated
  support in gdbserver.
