>Description:
	The ns32k series cpus use three different methods to store constants.
	- Constants in data memory are stored in little endian byte order.
	- Immediate constants in the instruction stream are stored in
	  big endian byte order.
	- Immediate addresses in the instruction stream are stored rll
	  encoded in big endian byte order.

	The ns32k relocation records encode this in the r_disp field.
	gas/ns32k sets this field correctly. But relocation records
	for vector fields created by ld have not set this field correctly.
	Due to this entries in the global destructor/constructor table are
	stored in the wrong byte order.

>How-To-Repeat:
	Try to run a program that uses libg++.
>Fix:
	Apply the following patch to ld. I hope RELOC_INIT_SEGMENT_RELOC
	is intended for this purpose.
