	(ld_so_xfer_auxv, memory_xfer_auxv): New function.
	* auxv.h (procfs_xfer_auxv): Remove comment.  Rename to ...
	(memory_xfer_auxv): ... here.
	* linux-nat.c (linux_xfer_partial): Rename procfs_xfer_auxv to
	memory_xfer_auxv.
	* procfs.c (procfs_xfer_partial): Likewise.
	* solib-svr4.c (svr4_relocate_main_executable): New prototype.
	(svr4_special_symbol_handling): Call svr4_relocate_main_executable.
	(svr4_solib_create_inferior_hook): Conditionalize the
