powerpc64-linux crtsavres.o

[Alan Modra]

I've just checked in the following to mainline, and will commit to
3.1 in a moment, approved privately by David Edelsohn.  ENDFILE_SPEC
from rs6000/sysv4.h wants crtsavres.o, and it was either this or
duplicate ENDFILE_SPEC in rs6000/linux64.h

	* config/rs6000/t-linux64 (EXTRA_MULTILIB_PARTS): Add crtsavres.o
	Add rules to make null object file.
