	* target.c: Include "gdbcore.h".
	(get_target_memory, get_target_memory_unsigned): New functions.
	* target.h (get_target_memory, get_target_memory_unsigned): Declare.
	* ppc-linux-tdep.c (ppc64_linux_convert_from_func_ptr_addr):
	Use get_target_memory_unsigned.
	* Makefile.in (target.o): Update dependencies.
