[Darwin, PPC] Move the out of line register save/restore to an endfile.
We have been including this in libgcc, which means that we have to append
-lgcc even when using shared libgcc. In preparation for revision of libgcc
split this into an endfile.

* config.host: Add libef_ppc.a to the extra files for powerpc-darwin.
* config/rs6000/t-darwin: (PPC_ENDFILE_SRC, PPC_ENDFILE_OBJS): New.
Build objects for the out of line save/restore register functions
so that they can be used for any supported Darwin version.
* config/t-darwin: Default the build Darwin version to Darwin8
(MacOS 10.4).
