Currently it fails with gcc from sdk 2.1 because of a spec change [1].
Maybe we should start using the definitions from spu_mfcio.h.

Add the source code that is used to generate spu_save_dump.h and
spu_restore_dump.h. Since a full spu tool chain is needed to
generate these files, the default remains to use the shipped
versions in order to keep the number of tools for building the
kernel down.
