* corelow.c (add_solib_stub): Remove copying of to_sections,

pass current_target to SOLIB_ADD. The Sep 10 change failed
	if SOLIB_ADD errored out, or if SOLIB_ADD was trying to access
	target memory.
	* corelow.c (core_open):  After reading the shared libraries,
	copy the modified to_sections vector from current_target to
	core_ops, so that core_close can free it later.
	* config/rs6000/nm-rs6000.h, rs6000-nat.c (xcoff_relocate_core):
	Pass down target parameter from SOLIB_ADD and use it instead of
	directly accessing core_ops.
